@hee-haw 65 and have struggled all my life. Homeschooling my grandchild now so feeling determined to get it. This is really helping. Pretty sure I have what is called dyscalcula. I have to keep reminding myself of steps
Lisa McArthur you can also just times the 1st number by the second then devide it by 100 so 30% of 30 is 30×30÷100= answer 58% of 95 is 58×95÷100= answer both ways are simple and great

*So basically..* _with zeros_ 50% of 100 5 x 10 = 50 _with zero percentage and without zero base number_ 40% of 15 4 x 1.5 = 6 _without zeros_ 43% of 127 4.3 x 12.7 = 54.61 _vice versa with the second statement_ 27% of 120 2.7 x 12.0 (or just remove the zoro) = 32.4 i feel ashamed of myself.
Haxy Go Haxy Go This is just floating point math. You probably learned it using scientific notation in school. Always multiply the base numbers and use the powers of ten to determine where to move the decimal point. 27% = 27×10^-2 120 = 12×10^1 27×12 = 324 -2+1=-1 So move the decimal left by one: 32.4
@Monika gee Agreed. My job is by no means mathematically complex, but I use algebra and statistical methods almost every day of my life, both personally and professionally. If you needed this video to learn this stuff, you are not very bright....at all.
That's because you can't use systems that aren't in the core curriculum, I always thought that if you get the right answer it shouldn't matter how you get the answer.
What's also sad is that this "new" new math makes no sense in teaching math calculations in such a complicated way. Or worse, the children are expected to only do the math the "new" way and they don't even know how to do long hand/short hand division, for example, AND dodge learning it as if it makes your brain hurt to think that hard. But, that's also the deliberate dumbing down of children.

Thank you so much. I thought I was stupid but clearly not. Always knew the simplicity in life works. My brain feels nice and relaxe. You have a calm influence too
I am actually feeling so much better now in math thanks to you😆I actually understand what you teach and omg how much i wish i had you as my math teacher😭 I actually studied for a math exam using your videos to study from and i am feeling good about the exam and i only left about 3-4 questions empty but the rest of the whoooole exam i finished! Maybe i will get some of those questions wrong and i maybe wont get the grade i want for it but for once i actually felt good for a math test, so thank you so much, you really helped me and tomorrow i have a precent checkpoint and i am preparing myself for it!
Same,within just a second I can solve some problems and work out the solution (even if it's approximated) quicker than I would do before without my calculator. tecmath keep up the good work
It’s the state department that dictates what and how the teachers teach. We would all teach this way and the old fashioned way if we could. Life in the classroom would be so much easier if we weren’t dictated as to how we have to teach.
I don't know why this was in my suggestions, I hate Maths! But, I now feel like I've been lied to my entire life! I've learnt more in this five minute video than I ever did in school!
***Me at school that took 1 hour math class and didnt even understand a single word**** ***me watching this video in just a minute and learned many things***
My father was in banking but my mother was wonderful at math. Thank God for her. I was slow in math but she taught me shortcut tricks. Now I find there are others. Thank you all for sharing.
this is great, I never knew how to do percentages in school, even if the teacher taught for a whole year. but now I know how to do it in only 5mins. I am looking forded to your next videos.
omfg thankyou so much, you just saved me from failing my exam today.. ive been studying all day and night & this is the only thing thats made sense lol
The main percentages you’ll see are 25%, 50% and 75%. 50% is easy since you just divide the number in half. Then you just divide that answer in half and you get your quarter (25% and 75%) and then do a little addition or subtraction. Another cool trick is if the digits making up a number are added together and their sum equals a number that’s divisible by 3, then your original number is also divisible by 3. Example: 354 is divisible by 3 because 3+5+4=12 and 12 is divisible by 3. Another one is the 9 times table. From 9x1 up to 9x10, the numbers are inverted. So the pattern starts with 9x1 through 9x5: 09, 18, 27, 36, 45 and then at this point it inverts and the numbers are backwards for 9x6 through 9x10: 54, 63, 72, 81, 90. I love little tricks like that :)
I learnt the rainbow method of multiplication from you. I then started to do percentages by multiplying first then adding a decimal point to get the percentage. I always had a fear of maths before I started watching your videos, now I do sums in my spare time. Thanks for the great work.
Or maybe it y'all fault for not researching about maths in internet. I just searched a little bit of it and already got this in my recommendation and thank god I'm still in school.
Thank you! I thought I could do percentage problems then I realized that I was only doing percentage problems with high numbers ( to estimate capital gains on the srock market, years ago ). Doing percentage problems with small numbers is totally different.
My appreciation for these videos are immeasurable, it’s a huge shame though that mental math is rarely incorporated into the typical school mathematics curriculum. Hopefully that will change in the future. Regardless though, keep up the helpful content :)
It should be obvious even without the video- 60% of a number = 0.60 times the number. Of course, I say "should be obvious" since it definitely won't be for everyone- I haven't used percentages in some time so I forgot about it too :P
when i watch these i just get so happy bc I feel so smart and you have no idea how much you help me out in class!! especially since I have a math final tomorrow :/
tecmath i got a B!!! thanks so much, a B might not be great to others but i usually don’t get good grade so i’m really proud of it, your video really helped me!
At 58, I could not stand math--no thanks to my dad and instructor. No patience on their part. This was so very helpful. It's all in the pitch. Thank you.
I could never do this in school. Yet I've just learnt this in the video. It's easy and you have explained it better than any teacher I have been taught by. Thankyou so much.
I wish I could show this to my teachers from grade school through highschool. I'm sure they never knew this. They DAMN sure never told me, those bastards!
I'm 73 now. When I was in school, teachers would be shouting at kids because they couldn't grasp simple tasks. They didn't realise, the poor kids were probably dyslexic. The kids were petrified, which would make them even worse.
Thankfully there is change on the horizon. There are now schools without classes, year levels and even subjects. Children are empowered to teach themselves. We teach the children how to learn, not what to learn.
@Steven Lee Steven, right decision when we take into account today's school scenario. If teachers fall short, the children's attitude most times falls shorter. I'm a retired teacher and was singularly fortunate with my pupils. Today it's hard . Hey, Steve, why not take up online teaching ? Needs some effort and innovative ideas/hacks initially, but the end product is profitable and no hassels compared to teaching a class with rowdies. GOD Bless and All d Best.
Remarkably, this is the only trick he has taught that is more difficult than whatever I do in my head. Take what I can from his teachings and apply what is useful.
Wow you're the smartest person in the world, that method definitely wasn't shown at the start of the video. You deserve an Oscar. If you say it wasn't shown, then check 00:48 for example
Yea or just in case you don't have a calculator a simpler way to do it just simply multiply both numbers together and then write your answer like you would dollar amounts for example like the last problem of this video was 65% of 82 you would multiply both numbers together 65x82=5330 then you would just write it out as 53.30 or for example the other problem 60% of 130 you would multiply 60x130=7800 which would be 78.00 or 78 hope this makes sense as well
At a glance I got the method omg if I had known this 65 years ago i don't know where I would have been..thank you for sharing your knowledge stay blessed ❤️
For that last one I just looked at 65% and thought of it as 50% + 10% + 5%. 50% of 82 is just half, so 41. 10% of 82 is 8.2, and 5% of 82 is just half of the 10%, or 4.1, then just add 41 + 8.2 + 4.1 = 49.2+4.1 = 53.3. It requires a bit more intense memorizing though holding 3 numbers in your head and adding them one by one.
How about this, i have just bought some new shirt, the price is $80 and it's discount by 50%, so, I just have to pay 40 dollars right? and the next day i saw the same shirt with the same price but this time the discount is 70%, So, if I use the method above, I have to spend more money than before, which is 56 dollars, am i right? or there are difference between "Percentages & Discounts"
It's important to clarify if 80$ is the discounted price or the original price. If it's the original, 50% of 80$ is just 40$. Another important thing to clarify is: Is the discount 70% off, or is the new price 70% of the original? 70% off means you're subtracting the 70% from the original price, so 80 -80x.7 like mentioned by I'm nahraf. You can also think of it as 30% of the original price since if you take away 70% of the 100% price of 80$, you're left with 30% of 80, or 24$. If you say the new price is 70% of the original price, this means the new price is 0.7 x 80 = 56$. Discount and percentage: Discount means you're taking away or reducing an amount of something, whether a price or quantity of things. A lot of times calculated by percentage. Or x amount off. For example: a 10 dollar discount or 10% discount. A percentage is a proportion of the whole, if the whole is 100%. Its a numeric way to represent a value compared to a previous base value. For example: a 50% decline of a population, or 12% of cars in the US, or 25% off a price in a store.
oh ok sir..., by the way 70% is the discount not original or new price, the price is still $80, i almost forget it...., thank you for your advice sir :)
I can't believe you made this so easy... I'm taking my GED at the age of 36 and a lot of the questions are percentage-based and they want you to go through a lot of hoops to get the answer... This made it so easy. Thanks a ton.

both ways are simple and great

I am actually feeling so much better now in math thanks to you😆I actually understand what you teach and omg how much i wish i had you as my math teacher😭 I actually studied for a math exam using your videos to study from and i am feeling good about the exam and i only left about 3-4 questions empty but the rest of the whoooole exam i finished! Maybe i will get some of those questions wrong and i maybe wont get the grade i want for it but for once i actually felt good for a math test, so thank you so much, you really helped me and tomorrow i have a precent checkpoint and i am preparing myself for it!
I learnt this in my late 30s. From you. Just now.
I feel robbed.
Months of teaching gets CRUSHED by this 5 minute video. My guy, you saved my life!
I wish you were my teacher you are amazing
Same,within just a second I can solve some problems and work out the solution (even if it's approximated) quicker than I would do before without my calculator. tecmath keep up the good work
+AWESOMEGAMER HD ikr hes awesome and my teachers suck her rocks!!!
AWESOMEGAMER HD I know
AWESOMEGAMER HD yeah me too
Very good, you’ve inspired me to start remedial maths lessons at the age of 64!
Teachers: -We will put everything they learnt in the test-
Also teachers: We will put questions mankind can’t answer
FAXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX!!!!!!!!!
Sometimes it's not the teachers, it is the people in charge of the Curriculum and teachers have to follow it.
true true
It’s the state department that dictates what and how the teachers teach. We would all teach this way and the old fashioned way if we could. Life in the classroom would be so much easier if we weren’t dictated as to how we have to teach.
58 years later and I have finally worked out how to do percentages, thanks to your very clear video.
This would've saved me countless nightmares back in school.
I don't know why this was in my suggestions, I hate Maths! But, I now feel like I've been lied to my entire life! I've learnt more in this five minute video than I ever did in school!
***Me at school that took 1 hour math class and didnt even understand a single word****
***me watching this video in just a minute and learned many things***
Same
Same man 👨
Same
same😃
*same here*
My father was in banking but my mother was wonderful at math. Thank God for her. I was slow in math but she taught me shortcut tricks. Now I find there are others. Thank you all for sharing.
this is great, I never knew how to do percentages in school, even if the teacher taught for a whole year. but now I know how to do it in only 5mins. I am looking forded to your next videos.
nice
omfg thankyou so much, you just saved me from failing my exam today.. ive been studying all day and night & this is the only thing thats made sense lol
I wish you were my math teacher you make things much easier than my math teacher
+Logan Rogers lol me too
+Logan Rogers Same i hate mine
same
me too
I never thought I would learn this but this guy is a life saver bro hope u get everything you want and you you saved and helped lots of kids.
The main percentages you’ll see are 25%, 50% and 75%. 50% is easy since you just divide the number in half. Then you just divide that answer in half and you get your quarter (25% and 75%) and then do a little addition or subtraction. Another cool trick is if the digits making up a number are added together and their sum equals a number that’s divisible by 3, then your original number is also divisible by 3. Example: 354 is divisible by 3 because 3+5+4=12 and 12 is divisible by 3. Another one is the 9 times table. From 9x1 up to 9x10, the numbers are inverted. So the pattern starts with 9x1 through 9x5: 09, 18, 27, 36, 45 and then at this point it inverts and the numbers are backwards for 9x6 through 9x10: 54, 63, 72, 81, 90. I love little tricks like that :)
It’s 9pm and I’m learning how to do percentages by the shark from finding nemo. Amazing!
Awesome dude! Now I'm thinking of him I my head as Bruce😆
Underrated
i am 7 yr and i learned this trick in 5 min you are so good teacher love from india
love from india too lmao
I learnt the rainbow method of multiplication from you. I then started to do percentages by multiplying first then adding a decimal point to get the percentage. I always had a fear of maths before I started watching your videos, now I do sums in my spare time. Thanks for the great work.
I will be a good parent thanks to this 😁😎... homeworks handled!👌🏾
Good luck to you and your kids
I see this NOW? Right when I'm about to graduate?!?!?
PantryMonster good thing I got I now I'm only going to middle school when school starts again
Hahahaha sad life.... But still, a congtraz on advance...
PantryMonster hahaha yes!
Me too..I am now about to graduate in my degree.but because I'd like to pass Civil Service exam I need to feed my mind about math..tricks..
Or maybe it y'all fault for not researching about maths in internet. I just searched a little bit of it and already got this in my recommendation and thank god I'm still in school.
I am so baffled at this! Thank you so much! I wish teachers would teach us this rather than try rack our brain and learn the hardest way!
I dreaded maths at school, hated percentages, this guy is great! Thank you!!! Learnt on this than years at school!!! Thank you...
Thank you! I thought
I could do percentage
problems then I realized
that I was only doing
percentage problems
with high numbers ( to
estimate capital gains
on the srock market, years
ago ). Doing percentage
problems with small numbers
is totally different.
wow thank you so much you also made my day, it's so sad that school take up 6 hours of the day when you only need 5 minutes to learn percentages
My appreciation for these videos are immeasurable, it’s a huge shame though that mental math is rarely incorporated into the typical school mathematics curriculum. Hopefully that will change in the future. Regardless though, keep up the helpful content :)
My math teacher was teaching this for a week and my stupid unattentive ahh gets bored so I'm very glad that you made this short :)
Did anybody else discerned the shortcut simply by looking at the thumbnail?
carbon273 yeah i still watched tho to make sure xD
It should be obvious even without the video- 60% of a number = 0.60 times the number.
Of course, I say "should be obvious" since it definitely won't be for everyone- I haven't used percentages in some time so I forgot about it too :P
Yes I got
You could also think with your head to understand that it's not a shortcut but how you always calculate percentages
Your videos are worth for us IBPS students.
when i watch these i just get so happy bc I feel so smart and you have no idea how much you help me out in class!! especially since I have a math final tomorrow :/
Thank you and good luck. Please let us know how you go!
tecmath i got a B!!! thanks so much, a B might not be great to others but i usually don’t get good grade so i’m really proud of it, your video really helped me!
@@eva2.029 congratulations! Your should be proud of yourself! Well done!
@@eva2.029 ayy bs and cs get degrees :) be is a really good grade, no matter what other people say
If only I had math teachers like you I would not have had math anxiety!
At 58, I could not stand math--no thanks to my dad and instructor. No patience on their part. This was so very helpful. It's all in the pitch. Thank you.
Math puts me to sleep zzz
Susan better get this channel verified before it hits 1 million subscribers
Thank you sir! I'm a 29 year old who still struggles with maths and you taught me a lot about percentages.
I could never do this in school. Yet I've just learnt this in the video. It's easy and you have explained it better than any teacher I have been taught by. Thankyou so much.
I wish I could show this to my teachers from grade school through highschool. I'm sure they never knew this. They DAMN sure never told me, those bastards!
I'm 73 now. When I was in school, teachers would be shouting at kids because they couldn't grasp simple tasks. They didn't realise, the poor kids were probably dyslexic. The kids were petrified, which would make them even worse.
Thankfully there is change on the horizon. There are now schools without classes, year levels and even subjects. Children are empowered to teach themselves. We teach the children how to learn, not what to learn.
Steven Lee idiot
@Steven Lee Steven, right decision when we take into account today's school scenario.
If teachers fall short, the children's attitude most times falls shorter.
I'm a retired teacher and was singularly fortunate with my pupils.
Today it's hard .
Hey, Steve, why not take up online teaching ? Needs some effort and innovative ideas/hacks initially, but the end product is profitable and no hassels compared to teaching a class with rowdies.
GOD Bless and All d Best.
IMAGINE PEOPLE ON YT TEACHING BETTER THAN MY ACTUAL TEACHER
Remarkably, this is the only trick he has taught that is more difficult than whatever I do in my head. Take what I can from his teachings and apply what is useful.
this mans voice is so relaxing
Omg! Where have you been all these years????
I’m actually watching this video during my winter break and I don’t regret it... I have to get ready for my math class in the spring semester 😭
I am dyslexic and never could get a handle on math....but this, OMG, thank you soooooo much for being the first to help me properly understand math.
I just finished college calculus and this lowkey blows my mind that I never knew about this
I hated maths like I hate asparagus. Where have you been all my life? I wish you were my maths teacher, would have helped a great deal 😭😭😭
Hate is the mis-understanding of a particular thing. As scared is to the same concept.
This is the way we were taught in Scotland in the 50s into the 60s, then a new form of teaching came in changing the whole premise.
Now I'm constantly told that Common Core is the new way to teach correctly.
Dumbing down is the new cool.
David de la Torre-Montaño same
are you from 50s, 60s ??? 😂
This was incredible. Thank you so much. It took less than 4 minutes for me to learn this.
I knew how he was going to explain the working out just by looking at the thumbnail😲!
just multiply them, then divide by 100. even easier.
That makes life SO MUCH EASIER
Yes it makes life much simpler.
THANK. YOU.
Wow you're the smartest person in the world, that method definitely wasn't shown at the start of the video. You deserve an Oscar.
If you say it wasn't shown, then check 00:48 for example
Yea or just in case you don't have a calculator a simpler way to do it just simply multiply both numbers together and then write your answer like you would dollar amounts for example like the last problem of this video was 65% of 82 you would multiply both numbers together 65x82=5330 then you would just write it out as 53.30 or for example the other problem 60% of 130 you would multiply 60x130=7800 which would be 78.00 or 78 hope this makes sense as well
I love how my Pre-Algebra class is learning this and I just got recommended this video 😂
At a glance I got the method omg if I had known this 65 years ago i don't know where I would have been..thank you for sharing your knowledge stay blessed ❤️
For that last one I just looked at 65% and thought of it as 50% + 10% + 5%. 50% of 82 is just half, so 41. 10% of 82 is 8.2, and 5% of 82 is just half of the 10%, or 4.1, then just add 41 + 8.2 + 4.1 = 49.2+4.1 = 53.3. It requires a bit more intense memorizing though holding 3 numbers in your head and adding them one by one.
How about this, i have just bought some new shirt, the price is $80 and it's discount by 50%,
so, I just have to pay 40 dollars right? and the next day i saw the same shirt with the same price but this time the discount is 70%, So, if I use the method above, I have to spend more money than before, which is 56 dollars, am i right? or there are difference between "Percentages & Discounts"
no u just pay 80$ - (80$ × 70%)= 24
It's important to clarify if 80$ is the discounted price or the original price. If it's the original, 50% of 80$ is just 40$.
Another important thing to clarify is: Is the discount 70% off, or is the new price 70% of the original? 70% off means you're subtracting the 70% from the original price, so 80 -80x.7 like mentioned by I'm nahraf. You can also think of it as 30% of the original price since if you take away 70% of the 100% price of 80$, you're left with 30% of 80, or 24$.
If you say the new price is 70% of the original price, this means the new price is 0.7 x 80 = 56$.
Discount and percentage: Discount means you're taking away or reducing an amount of something, whether a price or quantity of things. A lot of times calculated by percentage. Or x amount off. For example: a 10 dollar discount or 10% discount.
A percentage is a proportion of the whole, if the whole is 100%. Its a numeric way to represent a value compared to a previous base value. For example: a 50% decline of a population, or 12% of cars in the US, or 25% off a price in a store.
oh ok sir..., by the way 70% is the discount not original or new price, the price is still $80, i almost forget it...., thank you for your advice sir :)
i get it...., thanks :), how about this 40% of 1.300.000? should i remove all zero of 1.300.000? or....
I have a math test on Monday 😂😂😂😂. I'm watching all your videos lol
I FOUND THIS A DAY AFTER I HAD A NO CALCULATOR TEST ON THIS!!!
I am now 35 years old and percentages had never been so easy for me to understand until this very moment. Thank you for this video.
Bro how didnt u go down in history-
This actually helped me so much, thank you 😊
NOW RUclips RECOMMEND ME THIS! After all these years, yeah.
I can't believe you made this so easy... I'm taking my GED at the age of 36 and a lot of the questions are percentage-based and they want you to go through a lot of hoops to get the answer... This made it so easy. Thanks a ton.
Good luck with your GED.
If teachers have RUclips account this should be in the recommended list
