Math trick - multiplication of numbers in their twenties! 

So many people have gone through their life thinking they were stupid because they couldn't understand mathematics, but what you have shown us is; the problem was with the teacher, not the student. Thank you for your clear and concise explanation of mathematical concepts we were never taught in school, and for making us realise we were not stupid, we simply weren't taught correctly.

Nice strategies for sure! Very efficient way to explain! Great job! Many students will save and time when they multiply two digit numbers like this.

Brilliant! If only someone had taught me this method 60 years ago! Thanks so much.

Truth, I AM learn more from you tube than school.

Always first for learn trick @tecmath

Your videos are very helpful for competitive exams, a big thanks to you. 🤩

Thank you!

Awesome trick

Thank You.

I love this channel 🥰

Hello, your videos are really great😀! Learning and enjoying tricks in my 30s and sharing ur videos with kids in schools and colleges. I have two requests or suggestions, it would be great if u consider them. 1. Pls add subtitles in english too, not all people are native English speakers. It would be easy to follow while you speak. 2. Please put a more descriptive title or description. For e.g you have multiple videos for easy multiplication tricks but they have different rules or fall into different category of numbers. Like this video clearly tells the trick is for number in twenties! 😊

Another good one. I was just thinking about your channel this morning when I was planning a long distance drive. I was trying to work out how much quicker I'd be driving at 80mph (illegally!) than sticking to the legal limit of 70mph. The journey was a few hundred miles or so, but that wasn't totally relevant, I was just trying to consider a quick way of working with per hour/minute calculations. I couldn't think of one!

This is awesome !! thank you ...

My mind expanded

I was the big fan of yours :D

More videos neededdddddddddddd

I REALLY like this trick. Thank you so much!

Thes tricks are ultra cool and amazing

Really enjoying your videos thanks so much for the help. 👍 Can you do a Speed, distance, time tutorial please?

Thanks a lot

This was really cool thank you! And the voice is Awesome! God bless stay safe.

How come? Here's the logic: That's basically like (x+a)(x+b) where the x is 20. And the x times 3 times: x.x; x.a; x.b. That will become like (x+a+b)x Like the example 26x23 That will be like (20+6)(20+3) That's how you find 29x20, from (x+a+b)x --> (20+6+3)20 And the last is (a.b) which is 6x3, like how you do with (x+a)(x+b)

😄😆💚🤗 thanks for the fun exercises 🤗💚

Great tech mate 👍

Thank uuuu❤

Very Nice Trick Sir. This is the best method to multiply.

👍👍👍👍👍

It can be applied on 30's if you multiply by 30, and maybe others as well on the same principle.

I love Thor like peoples ❤❤🤙

Sharing👍🏻🎁

Thanks Chris hemsworth for the lovely math

Very clever, but I really think that I could arrive at the answer faster by punching the numbers into a calculator than I could by carrying out these mental manipulations.

Found most pretty easy to follow, but this one takes the same time as the way i am already used to..so this one isn't that different in time. I am however trying to remember if your voice is from one of those travel show's or someone I used to work with a few year's back. Tall slim and initials are BP. Your voice is very familiar though.

I learn this trick from my mental math book.

Remeber me?

HIII

All numbers are near each other .what I wondered what could I do with such as numbers not near eg 27 by 52.

First!

Wow..

this is all very cool, but at my ripe old age I don't need it. I now use my calculator...who doesn't have one?

Nothing special

GET TO THE DAMN POINT
