I can totally relate. I'm 43 and I never liked school. Incompetent teachers, useless subjects rarely anyone has interest in, and the lack of practical applications/experiments to spark interest in a given subject. I believe I'm a lot more intelligent today than I was back then. I never liked history, geography, or biology, but have tons of interest in psychology, quantum physics, and astrology. Chemistry, on the other hand, seemed like rocket science back then, however, I self-studied parts of it 5 years ago and found it to be fairly simple. It's amazing how the education system isn't really educating most of us, but seems to be more about discipline, obedience, and following rules. It's more of a brain-conditioning institution than anything else. Creativity has no room there, memorization is celebrated and rewarded, just as if that's what Tesla and Einstein did.
Josh - for the past two days I have watched your many math vids and refreshed my memory of fractions and percentages. Your brilliant way of teaching is super helpful, esp if you haven't been to school in a while - HIGHLY RECOMMEND your vids over the others. THX
Where were you when I was learning math!?! I always paid attention but always struggled. Thanks so much for this teaching ! At 51yo I have a real desire to go back and learn these basics for myself! Glad to have found you!🙏❤️
This is my favorite video ever now. I’m 31 and never learned these tricks until this video 😭 I really think the school system just hated their students
I just took probability and decided to get ahead of school, I never knew how to calculate percentages now I can do it no prob! thank you for the amazing video
I’m a teacher and I do teach this. Oddly enough some parents will blame me for teaching “common core math” when I show number sense strategies like this.
Study your basic add, subtract, fractions, multiple, ➗, protractor, triangle scale rule, standard ruler and metric system ruler, if school offer carpentry classes to learn how to make 25° angel to 45° angel. Carpentry wood work classes is harder than I thought it would be DC average grade was good enough for me. Lol
@@O-ShinSpringsWater and be sure to go to English class to learn that an "angel" is not an "angle" but you do know that for every girl that has the curves (some would call her an angel) there is a guy that has the angles.
That is very good and i want to be a teacher and teach the teenagers things you didn't know about school and how to educate yourself and parenting and tricks you didnt learn in school i want to be a secondary school teacher or year 7 teacher
Thanks to t=cm@th I aced the math portion of my entrance exam for my HVAC Union. At 53 I had not studied math in 35 yrs. Now I will be getting my full tuition paid for = $20k per year.
WOW! Finally at age 50+ 😂 How is it that I learnt how to do this in minutes, when I spent years at school struggling and still didn't grasp it 😁 Thank you. Ok, just gonna give my Maths teacher sister in law the heads up 😉
in india even though they kill our creativity they make our minds so sharp in maths and science that we fiigure out these things ourselves but still there is no limit to learning. Nice videos
This is an amazing video! I love all your math tricks. Studying for the MCAT right now. I honestly feel so dumb that I didn't recognize this myself with all the math studying I've been doing! I wish you were my teacher in highschool - ours were not so great.
@@paulrounding5260 learned to do this before grade five which was over 65 years ago. I do my restaurant bills that have HST of 13% all the time by using 15% and subtracting 2%. For the tip -- 15% of the cost of the restaurant prior to the HST. Oh, another way of doing the 15 x 13 --- memorize that 15 squared is 225 and then subtract 2 of the 15's or 30 and one is back to 195. Another useful square is 25 squared = 625. I used to know a lot more squares but did not find them useful very often so the HDD in my head became full and I had to uninstall some things and they were the first to go. The worst thing is that many math puzzles totally stump me but arithmetic is decent.
Thank you! I'm 30 years old and just worked out how to do percentages PROPERLY. I never understood it and just pretended I did because after asking the teacher for the 3rd time they thought you were stupid and stopped trying
Tuesday August 24th 2021 I have to watch several of your videos again because don’t understand some of this vital and valuable information ! Thank you ! New subscriber ! ❤️❤️❤️👍👍👍♥️♥️♥️🌺🌺🌺🌹🌹🌹🌷🌷🌷😊😊😊
Thank you so much tecmath now I know a easy fast way to do this and I passed on my school practie test just because of this video thank you so much and for that I got a new 💻 mac book pro and a iphone 📱 12 from my parents
The Easiest way is to determine what 10% is, Simply by Moving Decimal Point, Then if its 40% , Multiple that by 4. If it is 45% then add 1/2 of the 10% to that. Example 45% of 180. 10% is 18 4 x 18 is 72 5% of 18 is 9 72 + 9 = 81 Quick Logic chk, 50% of 180 = 90.
Several years back in one of my classes one of the students was lamenting that it was difficult to learn math. I began explaining the construction of math textbooks. While I was discussing this a math major was nodding in approval all the while. Suffice it to say that math textbooks are not constructed is a sequential pattern. I read of a math teacher in Texas who wrote a textbook in a sequential order (Chapter 1 presented a concept; chapter 2 expanded on it; chapter 3 completed the discussion). Thing is, he couldn't get the book published. Why? Math teachers don't teach in that order. They don't teach these tricks because they never learned them because of the way they were taught. This disjointed pattern naturally restricts finding little tricks that make learning math easier.
Okay, first of all: you are so quick and to the point and the tricks are very cool too, but I gotta say; I am *totally* staying even more for your personality 😦😆💕 You are SO much fun and you sound like an awesome person!! Thanks teach- keep 'em coming! :]
Math in class: 2+2=4 Math in homework: 4+8=12 Math in tests: if George left the train station at 5:00 PM, how far away would Jupiter be when Annie ate a cupcake? my brain: ... ;-;
These are some of the best videos I've ever seen! They are totally practical and easy one you get the hang of it! I'm going to be watching all of your videos! Great job, thank you very much!
I’m obsessed with percentages. Mainly because I’ve never understood how they work. Now that I understand them a bit more, it’s becoming more and more fascinating.
With values closer to common numbers; 50%,75%, etc. It's easier to start with that value and work down. So, for example. 45% of 22. Well, 50% is 11. therefor 5% is 1/10 of that, or 1.1 . So 11-1.1=9.9 A harder example: 21.4% of 49. OK, so 20% is double 10% - so 4.9x2= 9.8 (if you can't do that, then 2x5=10, subtract .2) 1% is 1/10 of 10%, so it's 4.9/10, or .49. .4% is 4/10 of 1%, or 4x1/10 of 1%. so .049, double is .098, double that is .196. 9.800+.490+.196=10.486 Break the number into figures that are easier for you: maybe you do 21.5% and take .1% out, or maybe 22% and take .6 out.
Commercials at the end may work better, while we’re thinking of it. Give us an equation and the answer afterwards. After we’ve learned. Love it ,thanks!

They need to teach it this way at school. This was how I learned percentage
when I was in elementary school in Vietnam!
Awesome. We never did get taught this way - just follow the formula!
They teach us a different way bur way easier and shorter
Thank you for this channel, I have always let math defeat me!
At 56 I decided I am going to learn how to do it even if it's the last thing I do!

Just brilliant... The way you make the maths so much easier with a voice to match... Just Brilliant!!!
Thanks Dave.
Brilliant. One child is dyslexic. So teaching these easy methods to both kids. They are so good. Why make it difficult when it can be easy!
Never knew about reversing the %, 32 to 50 example, great trick 👍🏻
Here I am doing spreadsheets and this comes up on recommended. This saved me a lot of time in the future I think.
Thank you for explaining these tricks! No more digging out the phone/calculator and spending ages trying to work math out the long way!
Fantastic as always.... Seriously much better than any school methods

Tip 3 never occurred to me but makes so much sense, since percentages are basically an extension of multiplication and division if you think about it

You are literally the best, I wish my teachers in school had been like you
Math god I happy that I found you sir. My 5 years of high school never thought me this. Thank you so much sir.
Why don't they teach this in school?
Because they know students are gonna come to learn from your channel anyway.
The math teachers weren't taught this way. So, that is not how they teach it.
I was taught myself this way 50 odd years ago, no tinternet then.

You can't teach thinking.
Just need to teach them how to do the math .... then the student needs to put forth effort in the gray matter.
