53 year old who hated math when young. Watched your first video on PEDMAS this morning and have crushed all the new vids that are popping up on my home screen on YT.

Yes, there are many professions that don't require understanding of math. Regardless, people benefit from a well rounded education through high school. There have been many very solid studies done regarding the benefits of a well rounded education. Generally, people who have a rounded education are better at many life skills such as general problem solving. I certainly don't think that beyond a first year in college that everyone needs to pursue higher math, but you probably have benefitted far more than you even know by having at least some education in a variety of subject matter, even subjects that you don't see as being directly related to your chosen profession.
@@yungsmile7546 Better yet, forget it altogether. Parentheses are the proper way of setting precedence in an expression. Worst of all, PEMDAS is just an American and French crutch. Mathematics is worldwide. In 11th grade our Advanced Math teacher took seven of us - her students - to UC Berkeley to listen to a presentation by Georg Polya. The renowned mathematician spoke and presented for about 40 minutes and never once relied on PEMDAS. It was memorable for more than that. Our teacher had a Karmann Ghia; it would carry four in a pinch. We had three lap-sitters and I was the smallest, scrunched into the rear window hat shelf. Who says math is boring?!.

I worked in Adult Education for many years, and I can't tell you how many people claim that they are bad at math. Unfortunately, too many of them got this idea from educators who themselves struggled with math. Having the right attitude about math is the first step to learning. The next steps are learning a skill, then practicing it, and then adding a new skill by building on the skills that you have mastered. This was a great video.
This was a sh!t video because an imprecise definition of a calculation is bound to cause errors, and possibly injury or death if used in engineering. Using this as an definition of a calculation is the very worst kind of example to set. It is bordering on negligence for a supposed maths question to be so badly expressed
I was so hopeless at maths that I was permitted to skip the final exams - this, after my father (who was also scared of the subject) trying to teach me and never getting anywhere. Strangely, however, I am super quick at my tables, and, if not pressed for answers, can usually get mental arithmetic problems done correctly, and faster than others who have the benefit of paper and pencil.
PEDMAS - Parentheses, Exponents, Division, Multiplication, Addition, Subtraction. If you follow that, then you should be right in almost all, if not all, of your math problem solving endeavors.
I have a question for you! I am a retired senior citizen and did pretty well in earning a good salary while working. During my 30+ years working, I never had a need for solving a problem like this! I learned arithmetic in the 8th grade and it provided all the math I needed. My question: Can you give me a practical example of how solving this particular problem could be of value to an ordinary citizen?
By being able to solve these equations indicates to academics and employers that you have an ability to learn to a specific level of education! What your employers saw was that you have attained a standard of Math education which they sought for the position they were hiring!
@@BraddersMusic Okay, I won't attempt to rebut your position. Before I was interviewed for a career position, I took a battery of tests that took a half-day. The interviewing and hiring supervisor told me that I had the highest score they had ever seen! The test had a lot of math and logic questions, but I did not use, or need, the advanced math. I will state that the job was not for a rocket scientist. I started as a management analyst, progressed to a program analyst, and finally became a program manager.
I lost my maths foundation as a kid as I had to go to clinic every month, and it was always maths that got missed. As a result in any technical subject like chemistry or physics I used to understand the principles, but as soon as maths became involved I got lost. Now at age 72, your lessons have switched the light back on. A little late maybe, but it's nice to finally be aware.
This equation should be written as (4+3)2 - (10÷2) to get the answer 9, otherwise the answer is 2. PEDMAS was not taught when i was at school in the UK in the 1960s and presented with this original equation the answer would be 4+3x2 equals 14, minus 10, equals 4 divided by 2 equals 2.
I am 65 and I was at school in the UK. I was taught BODMAS Brackets Over Divide Multiply Add Subtract. Answer is 9. Many people leave school after not learning what was taught to them. Ignorance is no defence for being wrong. Wrong is always wrong. Conversely in English the rule , "I before E except after C" has stopped being taught in schools now as there are more words that do not follow the rule than does. Forget AI and always insist on Real Intelligence. Take care and have fun.
@@dougbowyer The fact is that BODMAS is not a mathematical rule, it is a convention which I was never taught. I'm 71 by the way. Imagine relying on a convention to be understood when instead you could write the equation in such a form that nobody could misunderstand the order in which you solve it, which is what I did when I wrote "This equation should be written as (4+3)2 - (10÷2) to get the answer 9". To get the answer 2, you write it down as a fraction as (4 +3)2 -10 over 2 in which you calculate the top line (the numerator) first and then divide by 2, the denominator. There is no need for BODMAS as all anyone needs to do is simply to write clear equations in which you work in a sensible way from left to right in just the same way as you read my message to you and that, I suggest, is using real intelligence to ensure that everyone tackles the equation in the intended order and gets the same answer. Relying on a knowledge of a convention to determine the order of solving it is clearly not a good way and this video proves that point. Many people have produced different answers and this shows the deficiencies of BODMAS. You too take care and have fun.
Yay! I finally got a correct answer using PEMDAS and watching your videos. I wasn’t taught PEMDAS and never learned math. I had horrible teachers so I never liked math. Thx! I love your teaching style and I’m finally learning math! (Secret: I’m beginning to like math! Sshhh🤫)
@@bwilderd5082 - No, because of order of operations. Division takes precedence over Subtraction, so you have to solve that part BEFORE you can subtract the answer from 14.
Thank you. I didn't know P.E.M.D.A.S., which make it so much easier. All I knew was the P., and just went straight across and got 2. I just subscribed and I am psyched!
I appreciate this. I learned the order of operations as PEMDAS, in college. I had to do a lot of extra problems to really understand. Math was my weakest subject in high school, in college, it was my favorite. Numbers are non negotiable, there is only one answer, I like that idea. Thank you.
We use BODMAS as the acronym for the order B - Brackets, O - Order of powers or roots, D - Division, M - Multiplication A - Addition, and S - Subtraction.
Math has its own language. I wish more teachers would spend time teaching the language of math first. I got this problem correct using PEMDAS. I enjoyed your explanation of the order of operation. Thank you.
That would have really helped me get through algebra. Math kept me from becoming a medical doctor, because you know how important algebra is to diagnosing and treating patients. Instead I became a lawyer, no algebra there, and I can sue people, including doctors.
Order of operations always comes into play when parathesis are not in place. You have to do 10÷2 before doing any subtraction and addition functions(except what is in parathesis-those always come first).
@@garylewis4938 No, it doesn't. Your order of operations is a convention not a mathematical rule and there is no justification for it. In the absence of parenthesis or brackets you work out the sum from right to left in the same way that you read this sentence. The mathematical rule is that you do the sum in parenthesis or brackets first. Thus you start with (4+3)2 which equals 14, then subtract 10 and divided the result by 2 which equals 2. If the question setter wanted the division to be done first, they would have placed it in parenthesis or brackets to show that was what they wanted. Therefore the correct way is to write the equation so that there is no doubt what the order of operations is by placing the parenthesis or brackets where the question setter wants them to be applied. Thus for the answer to be 9 the equation should be written (4+3)2 - (10 divided by 2) and there would be no discussion on the order of operations. In conclusion, the order of operations convention that you believe should be applied is nothing more than a device to spread unnecessary confusion and unnecessary arguments. Equations should always have parenthesis or brackets to clearly show the order of operation as everyone would then be able to understand that and we would come to the same answer without any disagreement! Permas/BOMAS
I opinion that algebra is but a tool like writing with words, to communicate. [(4+3)2] - (10÷2) is fairest way to write this. Consistency, no confusion.
@@rich7447 absolutely. No different rules. ...have to know what you are doing before hand, what you want to know, if some math functions formulas ignore basic rules. Should stick to proper rules. Slang leads us astray.
I made straight A's in school until my first year in high school and I made a d in beginning algebra. My teacher told me that either you get it or you don't and you just don't get it. Moving on I went to college and I was required to take algebra I retook my high school algebra I had an excellent instructor who taught me the"rules" . I took every algebra class available at a bachelor's level. I majored in chemistry.
I have never seen that acronym ever. I am not young and when I was in college I had to take a business calculus class. After a test my much older teacher wanted to speak with me. He said my calculus was perfect but I lacked the skills to finish my problems correctly . He said I had a jole in my learning not a learning problem.
I think the flaw of this arithmetic presentation is the failure to put a bracket around (10 : 2). If that's how it was meant to be computed, it has to be shown clearly, regardless of the PEMDAS rule. Pls, remember arithmetic must not be treated as mere arithmetic. As in all applied math situations, it represents a problem to be solved, therefore the expression must not contain ambiguity for the solvers. In computer programming PEMDAS is built-in, but I still prefer to have clearer expression.
To be technical PEMDAS is part of the common computer languages, but others don't recognize it. Relying on it, instead of using parentheses for clarity, is a mistake. I'm a bit touchy about careless expressions in programs. Short form: I dealt with a loss of traffic on one of our microwave systems. All the channels worked but one. We had recently installed an update on the alarm and control equipment, and that was the problem. The new one had a bug: the second set of alarms were accessible with a command that should be &H10, but when somebody wanted to look at those alarms the new software sent 10 - the command to loop back T1 #10. Sloppiness like PEMDAS makes me lose sleep once in a while.
While parentheses can be added for clarification, they aren't required for this problem to be properly understood. The definitions and meanings of operations, symbols, etc... are written in such a way as to avoid ambiguity. Ambiguity only arises when arithmetic isn't taught properly, remembered correctly, or the test question is poorly written (which isn't the case with this problem).
The Answer is 9. The Rule is the Following: PEMDAS. Means you Do things in the Following ORDER. "Please Excuse My Dear Aunt Sally" 1. Parentheses 2. Exponent 3. Multiplication 4. Division 5. Addition 6. Subtraction *M or D can be in either order, and A or S can be in either order. Thus the Answer is: (4+3)2 - 10÷2, which is (7)times 2, that 2 is not an Exponent, minus 10÷2= 14-5=9.😎
The abomination that is PEMDAS is only recognized in the USA and France. It is a secret decoder ring that invites error through lack of consistency the world over. Use parentheses or go home.
I despised math so much until I understood functions. Now I love everything about math. Helping my niece with her homework helps a lot too. Excellent vid thanks for explanation. It was the × OR ÷ that made things a lot clearer.
PEMDAS should have been laid to rest decades ago. I first heard of it in 7th grade; our teacher acknowledged that it is a sloppy way to write expressions but the book we had at the time used it. FWIW, the science book we had ridiculed the hoax of continental drift, too. Why it is still in use is beyond me.
Because this "teacher" teaches acronyms (BODMAS, PEMDAS, BOBS, DMSRS, etc.), not Algebra. It is memorizing acronyms what matters; it is not logic and brains which matter, anyway. And it depends ( "Algebra depends") on the country you happen to be at a certain time (UK, CANADA. USA -and even the State, for example Minnesota, where DMSR is the correct one), to be "trained"). OMG! What a fake teaching.
Why do RUclipsrs love these "precedence of operators" gotchas? Even when writing software where a programming language compiler has officially documented and enforced rules about precedence of operators, it is still a good idea to put in explicit parentheses, and not rely on the compiler precedence, just to avoid any possible confusion for careless human beings who need to understand or maintain the software.
I wish I had a teacher that presented things clearly like you do when I was in school. To be honest though, I have never needed to know in my everyday life. I am sure more accomplished people use algebra in their lives-careers.
The actual correct answer is 2. You work from left to right and parentheses first. If you want the answer to be something other than 2, then you would have to rewrite the equation.
You are correct in that you work left to right. But you have to do multiplication and division before addition and subtraction. The answer is 9. Its baffling how so many people in all these videos forget basic math.
✨ Thank you very much! This video has REALLY HELPED my daughter bc I just couldn't remember! I remembered the parentheses were first but, had forgotten everything else so, you helped me as well! 😊❤
Was never taught this in school or I never remembered having been so , you have explained this so easy. Your saying is like resistor color code which I remembered easily.
I got it wrong because I did the division as 14 div by 2 instead of div 10 by 2. I never knew the m&d, a&s were to be done depending which came first left to right. Wow, I can't believe I graduated high school, even got C's in Trig.
In my American primary and secondary instruction, English was the only subject required each and every year. The mastery of English requires many years, but many humans begin talking at the age of 1. We spend much of our time talking. This defines us. We do not need mathematics to master what humans do, what other creatures cannot. We do need English to master mathematics (in America, the U.K. et cetera). Once natural language is applied, we discover that there never was a competition. Language is primarily a creative medium, but it is also the glue that binds us socially. Mathematics is the grand analytical tool that has enabled us to solve problems that natural language cannot. Otherwise, we would not have suspension bridges and thermonuclear weapons. Creativity trumps analysis every time.
.... when I was very young in school, I use to wondered how this type of math problem would be used in an average, normal day of life (ha)? I still don't understand why/how these simple / complicated math problems might be used in engineering or physics, etc.? I am 65 and its good to have a refresher course after all these years, beats playing solitaire!
TMI. answer not shown is 2. 4+3x2 which is 14 -10 which is 4 divided by 2 is 2. the 10/2 isn't in () so you wouldn't do that before subtracting the first part.
I am 60. when I studied it junior high school in Japan. that time I was14 or 15 years old I remember I studied chemistry that Avogadro number, Fleming's rule and basic thing almost same year, I think. in high school I studied calculus and physics. many people didn't enroll university, but high school student must study it. but no longar necessary to study advance math like before. after that Japanese economy going down. education is very important.

I worked in Adult Education for many years, and I can't tell you how many people claim that they are bad at math. Unfortunately, too many of them got this idea from educators who themselves struggled with math. Having the right attitude about math is the first step to learning. The next steps are learning a skill, then practicing it, and then adding a new skill by building on the skills that you have mastered. This was a great video.
This was a sh!t video because an imprecise definition of a calculation is bound to cause errors, and possibly injury or death if used in engineering. Using this as an definition of a calculation is the very worst kind of example to set. It is bordering on negligence for a supposed maths question to be so badly expressed
Wow. Thank you. I needed that refresher
So this is an engineering problem?@@edeledeledel5490
I was so hopeless at maths that I was permitted to skip the final exams - this, after my father (who was also scared of the subject) trying to teach me and never getting anywhere. Strangely, however, I am super quick at my tables, and, if not pressed for answers, can usually get mental arithmetic problems done correctly, and faster than others who have the benefit of paper and pencil.
PEDMAS - Parentheses, Exponents, Division, Multiplication, Addition, Subtraction. If you follow that, then you should be right in almost all, if not all, of your math problem solving endeavors.
I have a question for you! I am a retired senior citizen and did pretty well in earning a good salary while working. During my 30+ years working, I never had a need for solving a problem like this! I learned arithmetic in the 8th grade and it provided all the math I needed. My question: Can you give me a practical example of how solving this particular problem could be of value to an ordinary citizen?
By being able to solve these equations indicates to academics and employers that you have an ability to learn to a specific level of education! What your employers saw was that you have attained a standard of Math education which they sought for the position they were hiring!
@@BraddersMusic Okay, I won't attempt to rebut your position. Before I was interviewed for a career position, I took a battery of tests that took a half-day. The interviewing and hiring supervisor told me that I had the highest score they had ever seen! The test had a lot of math and logic questions, but I did not use, or need, the advanced math. I will state that the job was not for a rocket scientist. I started as a management analyst, progressed to a program analyst, and finally became a program manager.
@@maturefella Do you not consider High School math teachers as ordinary citizens?
@@BraddersMusic I don't understand your question! My high school math teachers were very ordinary citizens.
@@FishnChips136 Perhaps you are right! Maybe I could come up with a trendy, as well as revealing, ID like FishnChips!
I lost my maths foundation as a kid as I had to go to clinic every month, and it was always maths that got missed. As a result in any technical subject like chemistry or physics I used to understand the principles, but as soon as maths became involved I got lost. Now at age 72, your lessons have switched the light back on. A little late maybe, but it's nice to finally be aware.
This equation should be written as (4+3)2 - (10÷2) to get the answer 9, otherwise the answer is 2. PEDMAS was not taught when i was at school in the UK in the 1960s and presented with this original equation the answer would be 4+3x2 equals 14, minus 10, equals 4 divided by 2 equals 2.
I am 65 and I was at school in the UK. I was taught BODMAS Brackets Over Divide Multiply Add Subtract. Answer is 9. Many people leave school after not learning what was taught to them. Ignorance is no defence for being wrong. Wrong is always wrong.
Conversely in English the rule , "I before E except after C" has stopped being taught in schools now as there are more words that do not follow the rule than does.
Forget AI and always insist on Real Intelligence.
Take care and have fun.
@@dougbowyer The fact is that BODMAS is not a mathematical rule, it is a convention which I was never taught. I'm 71 by the way.
Imagine relying on a convention to be understood when instead you could write the equation in such a form that nobody could misunderstand the order in which you solve it, which is what I did when I wrote "This equation should be written as (4+3)2 - (10÷2) to get the answer 9". To get the answer 2, you write it down as a fraction as (4 +3)2 -10 over 2 in which you calculate the top line (the numerator) first and then divide by 2, the denominator.
There is no need for BODMAS as all anyone needs to do is simply to write clear equations in which you work in a sensible way from left to right in just the same way as you read my message to you and that, I suggest, is using real intelligence to ensure that everyone tackles the equation in the intended order and gets the same answer. Relying on a knowledge of a convention to determine the order of solving it is clearly not a good way and this video proves that point. Many people have produced different answers and this shows the deficiencies of BODMAS.
You too take care and have fun.
I was taught exactly like you. The question should have been written like this: (4+3)2 - 10/2
An add " = x " to your equation to make it totally unambigous.
I agree.
My answer was 2.@dougbowyer
I love your videos. You are really helping me understand it
Yay! I finally got a correct answer using PEMDAS and watching your videos. I wasn’t taught PEMDAS and never learned math. I had horrible teachers so I never liked math. Thx! I love your teaching style and I’m finally learning math! (Secret: I’m beginning to like math! Sshhh🤫)
Parenthesis first then multiplication and division then add /subtract ... Answer id 9
Yes it "id" lol. ;)
Wouldn’t there have to be parentheses around the 10 divided by 2? To get 9?
@@bwilderd5082 -
No, because of order of operations. Division takes precedence over Subtraction, so you have to solve that part BEFORE you can subtract the answer from 14.
You sum the equation backwards 10÷2=5 then the 4+3×2=14 14-5=9
Yes. I am shocked that there are 477 people (and there may end up being more) who insist despite the absence of more parentheses that the answer is 2.
Thank you. I didn't know P.E.M.D.A.S., which make it so much easier. All I knew was the P., and just went straight across and got 2. I just subscribed and I am psyched!
I didn't know that the number outside of 7 you had to multiple. I need to do a refresher course. Thanks.
d.) 9
0:03 pulled this before the Mc answers were available. 14-5=9
which is wrong. It would be the case if the 10/2 were in ( ) but since they aren't it goes 14 (the answer to the first part) -10 (or 4)/ 2 which is 2.
The answer is 9. Glad to know PEMDAS has not changed with all the new math that has surfaced over the last 50 years 🙂
That's what I got, too. I'm 58.
Alternative math?
Bedmas
PEMDAS has not changed, but people still apply it incorrectly :/
I appreciate this. I learned the order of operations as PEMDAS, in college. I had to do a lot of extra problems to really understand. Math was my weakest subject in high school, in college, it was my favorite. Numbers are non negotiable, there is only one answer, I like that idea. Thank you.
We use BODMAS as the acronym for the order B - Brackets, O - Order of powers or roots, D - Division, M - Multiplication A - Addition, and S - Subtraction.
That’s what I used too
Both methods are the same just different wording.
PEMDAS was not taught in school in the UK, hence got right answer 1st time. We use precedence OR to be explicit using brackets.
I'm in UK got taught BODMAS rule at school - Brackets, orders, division, multiplication, addition, subtraction. :)
It like totally is, but it'd called BODMAS. Brackets are called brackets in proper English.
OK, the O is "of", but close enough.
I was also taught BODMAS in the UK, way back in the fifties, and it was probably taught long before that.
Using PEMAS would give the right answer. Parentheses, Exponents(none here), multiplication, addition and subtraction.
I agree completely. The world would be a better place if PEMDAS was lost forever, replaced by parentheses.
I was taught to use BODMAS order of operation - Bracket, Of, Division, Addition & Subtractioon
Math has its own language. I wish more teachers would spend time teaching the language of math first. I got this problem correct using PEMDAS. I enjoyed your explanation of the order of operation. Thank you.
PEMDAS = Please excuse my dear aunt Sally aka Parenthesis, Exponents, Multiplication, Division, Addition, and Subtraction.
Answer is 9.
That would have really helped me get through algebra. Math kept me from becoming a medical doctor, because you know how important algebra is to diagnosing and treating patients. Instead I became a lawyer, no algebra there, and I can sue people, including doctors.
In Canada, we were taught the same. BEDMAS lol!!! Brackets, exponents, division, multiplication, addition, subtraction. Would this format still apply?
I wish I had a teacher that taught math the way you do when I was in school a long long time ago
I was always taught do what is the parentheses first then do everything in order as it appears. I get two
Exactly. That is why this equation should have been written as (4+3)2 - (10÷2) for the answer to be 9.
Exactly. He’s incorrect. The second set of brackets is missing.
Thank God I’m not the only one that came up with two. I thought maybe I was getting senile in my old age.
Order of operations always comes into play when parathesis are not in place. You have to do 10÷2 before doing any subtraction and addition functions(except what is in parathesis-those always come first).
@@garylewis4938 No, it doesn't. Your order of operations is a convention not a mathematical rule and there is no justification for it. In the absence of parenthesis or brackets you work out the sum from right to left in the same way that you read this sentence. The mathematical rule is that you do the sum in parenthesis or brackets first. Thus you start with (4+3)2 which equals 14, then subtract 10 and divided the result by 2 which equals 2.
If the question setter wanted the division to be done first, they would have placed it in parenthesis or brackets to show that was what they wanted. Therefore the correct way is to write the equation so that there is no doubt what the order of operations is by placing the parenthesis or brackets where the question setter wants them to be applied. Thus for the answer to be 9 the equation should be written (4+3)2 - (10 divided by 2) and there would be no discussion on the order of operations.
In conclusion, the order of operations convention that you believe should be applied is nothing more than a device to spread unnecessary confusion and unnecessary arguments. Equations should always have parenthesis or brackets to clearly show the order of operation as everyone would then be able to understand that and we would come to the same answer without any disagreement!

4+3=7
7x2=14, 10/2=5
14-5=9
We learned this early in grade school 🤦🏽♀️ ✌🏽
14-5=9,so the answer is：D.9
9
I opinion that algebra is but a tool like writing with words, to communicate. [(4+3)2] - (10÷2) is fairest way to write this. Consistency, no confusion.
It wasn't confusing the way that it was written.
@@rich7447 One way fits all, or language misunderstanding.
@@consciouspi That's why language, and math, have rules. Order of operations is one of the more basic.
@@rich7447 absolutely. No different rules. ...have to know what you are doing before hand, what you want to know, if some math functions formulas ignore basic rules. Should stick to proper rules. Slang leads us astray.
When we learnt maths , this is how they gave with all the brackets. So it was very easy.
I made straight A's in school until my first year in high school and I made a d in beginning algebra. My teacher told me that either you get it or you don't and you just don't get it. Moving on I went to college and I was required to take algebra I retook my high school algebra I had an excellent instructor who taught me the"rules" . I took every algebra class available at a bachelor's level. I majored in chemistry.
Wow, that is awesome!
I have never seen that acronym ever. I am not young and when I was in college I had to take a business calculus class. After a test my much older teacher wanted to speak with me. He said my calculus was perfect but I lacked the skills to finish my problems correctly . He said I had a jole in my learning not a learning problem.
I think the flaw of this arithmetic presentation is the failure to put a bracket around (10 : 2).
If that's how it was meant to be computed, it has to be shown clearly, regardless of the PEMDAS rule.
Pls, remember arithmetic must not be treated as mere arithmetic. As in all applied math situations, it represents a problem to be solved, therefore the expression must not contain ambiguity for the solvers. In computer programming PEMDAS is built-in, but I still prefer to have clearer expression.
Just explain how you arrive at the answer leave the padding out of the video until the end .
To be technical PEMDAS is part of the common computer languages, but others don't recognize it. Relying on it, instead of using parentheses for clarity, is a mistake.
I'm a bit touchy about careless expressions in programs. Short form: I dealt with a loss of traffic on one of our microwave systems. All the channels worked but one. We had recently installed an update on the alarm and control equipment, and that was the problem. The new one had a bug: the second set of alarms were accessible with a command that should be &H10, but when somebody wanted to look at those alarms the new software sent 10 - the command to loop back T1 #10. Sloppiness like PEMDAS makes me lose sleep once in a while.
While parentheses can be added for clarification, they aren't required for this problem to be properly understood. The definitions and meanings of operations, symbols, etc... are written in such a way as to avoid ambiguity. Ambiguity only arises when arithmetic isn't taught properly, remembered correctly, or the test question is poorly written (which isn't the case with this problem).
Thank you for breaking the problem down. I have a better understanding of PEMDAS.
The Answer is 9. The Rule is the Following: PEMDAS. Means you Do things in the Following ORDER. "Please Excuse My Dear Aunt Sally" 1. Parentheses 2. Exponent 3. Multiplication 4. Division 5. Addition 6. Subtraction *M or D can be in either order, and A or S can be in either order. Thus the Answer is: (4+3)2 - 10÷2, which is (7)times 2, that 2 is not an Exponent, minus 10÷2= 14-5=9.😎
Yes so the answer is 2
I do agree the answer is "2"
4+3:7 x2:14_10:4 /2:2 is that fine or not
No you must do the division after the multiplication
I was wrong initially what I said@@danle161
Yes you are correct
Why does he and others not just write the equation in the correct form
The abomination that is PEMDAS is only recognized in the USA and France. It is a secret decoder ring that invites error through lack of consistency the world over. Use parentheses or go home.
I despised math so much until I understood functions. Now I love everything about math. Helping my niece with her homework helps a lot too. Excellent vid thanks for explanation. It was the × OR ÷ that made things a lot clearer.
At the title card, PEMDAS strikes again! My answer is d) 9.
(4+3)2 - 10/2
7*2 - 5
14 - 5
9.
PEMDAS should have been laid to rest decades ago. I first heard of it in 7th grade; our teacher acknowledged that it is a sloppy way to write expressions but the book we had at the time used it. FWIW, the science book we had ridiculed the hoax of continental drift, too. Why it is still in use is beyond me.
however the 10/2 isn't in ( ) so you wouldn't do it as 14-5; you'd do it as 14-10 (4) /2 which is 2.
The answer will be d) 9.
Why not simplify the equation by making the order of operation obvious? (4+3)2-(10÷2). Or if that's not obvious, then [(4+3)2]-(10÷2)
Exactly. If the 10 is supposed to be divided by the 2, indicate that with parentheses, not acronyms.
The order of operation is obvious, if you know the rules
Because that would not be confusing
Because this "teacher" teaches acronyms (BODMAS, PEMDAS, BOBS, DMSRS, etc.), not Algebra. It is memorizing acronyms what matters; it is not logic and brains which matter, anyway. And it depends ( "Algebra depends") on the country you happen to be at a certain time (UK, CANADA. USA -and even the State, for example Minnesota, where DMSR is the correct one), to be "trained"). OMG! What a fake teaching.
How about simplifying it to 9 = ?
I hated math/algebra in school, but even I knew proper order here. Answer is 9
Why do RUclipsrs love these "precedence of operators" gotchas? Even when writing software where a programming language compiler has officially documented and enforced rules about precedence of operators, it is still a good idea to put in explicit parentheses, and not rely on the compiler precedence, just to avoid any possible confusion for careless human beings who need to understand or maintain the software.
I'm not sure at all if precedence of operators is a "thing" in Pascal or Ada.
We struggle with math because math "experts" struggle with consistency. My 70s education has me at 2 .. 2024 has it at 9. I'm sticking with 2.
I don't know where you went to school, but my 70s education has me at 9, and it's still 9, so my 70s education didn't fail me today.
Funny how your answer isn't even an option.

This method is so crazy. In my days we worked on the numbers in parenthesis first: thus 4+3=7 x2=14 -10 = 4 divide by 2 = 2.
2 is the answer.
I am glad you brought this up! I was taught the same way as you were.
Again Jackson, Thanks for posting.
It's 4+3=7x2=14, but then you subtract 10/2, or 5, so the answer is 9. Do the multiplication before the subteaction.
I bet you could have made this video last a full hour without trying.
I wish I had a teacher that presented things clearly like you do when I was in school. To be honest though, I have never needed to know in my everyday life. I am sure more accomplished people use algebra in their lives-careers.
The actual correct answer is 2. You work from left to right and parentheses first. If you want the answer to be something other than 2, then you would have to rewrite the equation.
You are correct in that you work left to right. But you have to do multiplication and division before addition and subtraction. The answer is 9.
Its baffling how so many people in all these videos forget basic math.
Head of knuckle...
Based on him slowly teaching, made me Quit math. I fell asleep 😴
God, you are right! Speed it up.
Stupid math, why can't you just go from left to right? 4+3 is 7 times 2 is 14 minus 10 is 4 divided by 2 is 2. Math should be simple.
It's always the simple things!
@@shaneroberts3574 I agree .... KISS (keep it simple silly)
You are quite right. This is stupid Math made complicated. The answer is 2.

You were taking forever, like I had this on double speed and it still couldn’t hold my attention even as interested as I was.
PEDAL parenthesis - exponents - division multiplication - addition subtraction - left to right 9
Was never taught this in school or I never remembered having been so , you have explained this so easy. Your saying is like resistor color code which I remembered easily.
This was so helpful. Thank you!
Excellent review !!! 👍🏼
I got it wrong because I did the division as 14 div by 2 instead of div 10 by 2. I never knew the m&d, a&s were to be done depending which came first left to right. Wow, I can't believe I graduated high school, even got C's in Trig.
D) 9 no calculator. PEMDAS! Sad that some of my professors taught it wrong.
9 because of order of operations, brackets first, then parentheses, then multiplication and division, and addition and subtraction last
D) 9 PEMDAS
I had College Algebra; and I got it wrong. I forgot the rules. In my defense, I had that course forty-seven years ago.
Love your videos. Thank you!
In my American primary and secondary instruction, English was the only subject required each and every year. The mastery of English requires many years, but many humans begin talking at the age of 1. We spend much of our time talking. This defines us. We do not need mathematics to master what humans do, what other creatures cannot. We do need English to master mathematics (in America, the U.K. et cetera). Once natural language is applied, we discover that there never was a competition. Language is primarily a creative medium, but it is also the glue that binds us socially. Mathematics is the grand analytical tool that has enabled us to solve problems that natural language cannot. Otherwise, we would not have suspension bridges and thermonuclear weapons. Creativity trumps analysis every time.
.... when I was very young in school, I use to wondered how this type of math problem would be used in an average, normal day of life (ha)? I still don't understand why/how these simple / complicated math problems might be used in engineering or physics, etc.? I am 65 and its good to have a refresher course after all these years, beats playing solitaire!
TMI. answer not shown is 2. 4+3x2 which is 14 -10 which is 4 divided by 2 is 2. the 10/2 isn't in () so you wouldn't do that before subtracting the first part.
In the mnemonic e is for Exponents ...
