Luck? I’m 60 years old. I never liked Math, never passed math, and if I did, it was a miracle. I took 2 years of College level Math and I am proud to say… I worked this problem and got it right! Lol!
Why does this guy always say most people will get this wrong? Sometimes he doesn’t say what form he wants the answer in. Example, an improper fraction? Mixed fraction or decimal. Not a good teacher. In my opinion.
Wasn't the multiplication sign redundant? At first I mistook it as meaning 3x. But, since there wasn't an answer after the equal sign, I realized my mistake. I'm new to your program, but I don't think I've seen you do that before. In the end, I did come with the answer of 13.
We did this aged about 10 or 11nat school. BODMAS it was. Simple compared to multiplying and dividing pounds shillings and pence. I'd struggle to do that now but we did that at the same age. I can't have been more than 11, must have been 10 as decimal currency was brought in when I was 12.
Thanks for sharing these PEMDAS problems. I look at these with my grandson in 5th grade. He likes to do them in his head. He usually gets them correct. I need paper and pencil.
The multiplication symbol is not needed here. If the "x" referred to a variable, there would have been less space between it and the 3. The large space both before and after the "x" indicates that it is the multiplication symbol. From reading the comments, a couple of others are complaining that the "x" is a variable not a multiplication symbol, so you aren't alone in your thinking.
In the UK we don’t have the confusion between x as an multiply and x as a variable because x as a variable is written in cursive so that it looks like 2 c letters back to back. It is much less confusing.
I don't know if anybody else had this problem but what confused me with this is the "x" in the beginning of the problem (as in "3x") went from being a variable to becoming a multiplier ("3 times whatever followed) so instead of me saying "3 times 3", I saw it as "3x times 2", which gave me "3x + 7" and a different answer. How is it that the "x" in 3x went from being a variable to being 3 times something else?
I got 13 right away without even using any paper or pencil. Just followed the order of operations in its proper sequence. You should be able to do these in your head
Question- when looking at the problem, how do you know when x indicates multiplication or when it is a factor (?) as in x+y ?? I initially thought it would be 3x ‘times’ 2. I hope that made sense.
Look for an answer after the equals sign. Without knowing what it equals, you'd have no way to solve the equation, so that's a pretty good indicator. Also, if the problem is using the x as a multiplication sign (and not the dot, as some do), they'll typically use a different letter, usually y, for the missing value
Many years ago, before calculators, my algebra teacher insisted on showing the steps to work the problem, and counted it right even if you got the wrong answer, but got the steps correct!
So 49 ÷ 7 has to be read like 49/7? You calculate the fraction first and then subtract. So, could you write (49÷7), which according to PEMDAS is not needed?
There’s a subtle mistake in the explanation. It’s important to note that multiplication and division occur at the same time, left-to-right. Without this knowledge, someone trying to resolve 7 / 3 x 6 would mistakenly arrive at 7/18 instead of the correct answer, 14

Dear, oh dear, oh dear, I am 86, went to secondary school, leaving at the of 15. This “sum” took me about 10 seconds to get to the correct answer. Go back to the 40’s and 50’s and teach basic mathematics without such a yawning preamble.

Sorry this is not dyslexia it is dyscalcular not the same thing! If you have a reading problem it does not mean you have a maths problem but these are often confused even by those who should know!
With new CORE mathematics, the answer does not matter. So any number is correct. So 8 - 6 =176. 3 x 176 = 38. 49/7 = 21. 38 + 21 = 13. There. How did I do?

Really needs brackets around 49 divided by 7 I could argue that the answer is 9.28571 (6+49/7) >>> 55/7 Again depends on your age and where you were taught maths
@@jshend47 I'm British. I got my A Level Maths 35 years ago. 55/7 would be the answer using the method I was taught. Really need brackets around (49/7) to get the answer 13
According to the Order of Operations, any parenthetical expressions are evaluated, then exponential expressions, then any multiplication and division in the order of occurrence from left to right and finally, any addition and subtraction in the order of occurrence from left to right. Additional parentheses are not necessary if you truly understand how the Order of Operations functions.
So I know the answer is 13 because we have rules to mathematics. I'm just here to see all the comments by the self described brainiacs who think they know better than thousands of years of scholarly development.
My primary teacher touched on this in year 3 during one period. Never in my mathematical career since, have I seen such hogwash type equations. I will not be watching any more of the maths videos
For the love of god. Stop creating ambiguous bait problems like this to explain PEMDAS/BEDMAS. If a student of mine gave an answer of 55/7, I’d give them full credit. 13 is the bait answer, but it will screw you over in your professional career. It is understood that a division sign will always be the quantity on the left divided by the quantity on the right. If you want 13, use more parenthesis / brackets to eliminate the ambiguity.
Exactly. The answer you get will probably depend where and when you were taught maths. As a Brit who did "A" Level Maths,35 years ago, my vote is with 55/7
It MIGHT be ambiguous if he had left off the leading multiplication symbol then then you could argue multiplication by juxtaposition, but he didn't. There is no ambiguity here. The answer is 13.

Greetings. The answer is definitely 13. The expression given can be written as 3 x (2) + (49÷7) = 6 +7 =13.
Why did you put a times sign? Already the parenthesis indicates multiplication so It looks like 3x. Not 3 times.
Wasn't the multiplication sign redundant? At first I mistook it as meaning 3x. But, since there wasn't an answer after the equal sign, I realized my mistake. I'm new to your program, but I don't think I've seen you do that before. In the end, I did come with the answer of 13.
Yea, it was redundant. 3(8-6) is the same as 3*(8-6).
thank u
13 ... first the 8-6 (parentheses) then multiplication/division ... 3x2 and 49÷7 ... and then addition/subtraction (6+7). That's 13.
(8-6)=2
3×2=6
49÷7=7
6+7=13
13 PEMDAS in the house!!😊😊
So as I. I figured it out on my own and it turns out it came out 13 for my answer..
Learnt Bodmas in school, years ago, in UK, - so got the right answer :)
We did this aged about 10 or 11nat school. BODMAS it was. Simple compared to multiplying and dividing pounds shillings and pence. I'd struggle to do that now but we did that at the same age. I can't have been more than 11, must have been 10 as decimal currency was brought in when I was 12.

Love your problems and explanations. What grade level is this problem?
Year 3 primary
Thanks for sharing these PEMDAS problems. I look at these with my grandson in 5th grade. He likes to do them in his head. He usually gets them correct. I need paper and pencil.
Bdmas- brackets , division ,multiplication , addition then subtraction
Work the bracket first then division then addition
Before I even look at your solution, this is what I would do ...
3 x (8 - 6) + 49 / 7
3 x 2 + 49 / 7
3 x 2 + 7
6 + 7
13
Congratulation on making a straightforward calculation, complicated
Should have used the * or • sign to represent multiplication bc that looks like 3 x
In the original equation I read "3 x" as 3x. Is using the multiplication operator needed here? 🤔 Im a 52 year old trying to refresh my math skills.
The multiplication symbol is not needed here. If the "x" referred to a variable, there would have been less space between it and the 3. The large space both before and after the "x" indicates that it is the multiplication symbol.

Thanks for the responses. Appreciate it! 😊
The supercomputer between my years says the answer is 6 + 7 which equals 13 you figure 8 - 6 is 2 * 3 is 6 + 49 / 7 which is 7 so 6 + 7 equals 13.
What years?
I don't know if anybody else had this problem but what confused me with this is the "x" in the beginning of the problem (as in "3x") went from being a variable to becoming a multiplier ("3 times whatever followed) so instead of me saying "3 times 3", I saw it as "3x times 2", which gave me "3x + 7" and a different answer. How is it that the "x" in 3x went from being a variable to being 3 times something else?
That's why my answer was "minus 7/6"

Got it once again. Need to go to polynomials next or possibly trinomials
For once a problem without ambiguity.
Just need to know what order to use.
So why would you use a multiplication sign? I thought the problem was 3x(8-6) etc. The number to the right is always multiplication isn't it

there are no variables in this example. The 3 is being multiplied by the sum (9-6)
It’s not 3x it’s 3 times (8-6)+49/7. I suppose u could also do 3*(8-6). or 3 middle dot (8-6).
