How to Calculate Faster than a Calculator - Mental Math #1 

I clicked on this by accident, and now I'm a human calculator. Thank you!

another funny trick is - every 2 digit number times 101 gives this 2digit twice: 45 x 101 = 4545, 92 x 101 = 9292, 21 x 101 = 2121

This is actually really cool! Usually these things on yt shorts are fake and don't work, but this is actually true. Keep up the good work!

This is what should be taught in schools. Like this actually makes sense

STRAIGHT TO THE POINT!!! I was shocked but thank you so much!!

Man if you keep doing these vids i just might die out of happiness😅

finally the one math teacher that teached properly

So mind blowing video!!🤯 Thanks a lot.

97x94=(97x95)-97=(96^2-1^2)-97=9216-1-97=9118. Also, Trick 3 intrigued me, so I extended it! Its general form is definitely harder, but I think it's pretty cool, and especially useful for multiplying two *3*-digit numbers ending in 5. 45x125=? Start with 2x4x12+4+12=96+16=112. Since the result is even, divide by 2 (56), and add a 25 onto the end. 45x125=5625. 95x145=? Start with 2x9x14+9+14=252+23=275. Since the result is odd, subtract 1 (274), divide by 2 (137), and add a 75 onto the end. 95x145=13775. 345x615=? 2x34x61+34+61=4148+95=4243=odd, 4243-1=4242, 4242/2=2121, 345x615=212175.

Loved it Mahbub !! Thanks

WOw thank you very much for the trick this is actually really helpful and awesome!! u just earned a loyal subscriber!

Thank you man, actually very helpful and is straight to the point

amazing thanks for the vidoe

Thank lots for sharing 👍 💚 ❤️ 💙 😊

I wish we had learned Vedic math in our schools in Texas. I understand now why the greatest mathematicians are Indians. I never imagined that math could be fun.

So useful thanks for sharing great information 👍

I had found out about the first trick 11 while i was memorising the multiplication. Keep the journey, your video is so impressing.

This is so cool! Thank you!

Great job, thanks

Super class sir thankyou 🙏🙏🙏

94 is 6 shy of 100....100x 97 is 9700, that is 6 97s too many. 9700 - 600 (97 is 3 shy of 100) is 9100. 100 is 3 moree than 97, so we subtracted 3 too many, 6 times., so 6x 3 is 18...9100+18 is 9118

Amazing❤

Very cool! ^_^

Such a great teacher ❤❤

Good work , keep it up !

I am so lucky to find this video Thank you very much for your effort

Bro thanku 😊 ..easier

Pedantic point (I can't help it): "lightening" means making something lighter. The word you want is "lightning" which refers to an electric bolt from the clouds during a thunderstorm. I don't mean to take anything away from the point of the video, which is great content.

wow, impressive

Thanks.

Nice

Seeing a Bangladeshi teacher making these kinds of video feels so good. I am also from Bangladesh

this is actually crazy 🤠

This is so cool! Thanks for sharing!

Thanks U soo much for Ur efforts 😌😌🐱🐱

Mahbub come to save the day again.

Thank you sir 😇💪🧠

They make education more difficult than actual really is. Many reasons why and those reasons are in the best interests for the students.

These cases are really specific

Cool

This is pretty crazy you got a sub lol

Nice video. Pleased to see this from someone in bd❤

Love it! Thank you very much

Wow

Terima kasih penjelasannya

mr mahbub please switch with my math teacher 😭

He MASTERED the ENTIRE Eleven times Table❗🤯

You take the multiple of 10s nearest to any of the multiplier like in this 97*93=97*90 +97*3 in this case you already know there is a last zero in the right hand first side so the next multiplication is easier

Thank you now i calculate faster than Usain running

Lightning!

❤❤

Woow,didn't know this

this is super beautifull

wawawawa

❤

1000th like!!!!!!!!!!!!!

I’m ready for my test

Brother Mashallah ❤❤❤❤❤❤❤ u r really a masterpiece ....thnks sooo much ....I hope u will give us more and more info. Inshallah ....luv from kashmir brother ❤❤❤❤❤❤

97*93= (100-3)*(100-7)= 10000-100*(3+7)+21=10000-1000+21=9021+21=9021, or 97*96= (100-3)*(100-4)= 10000-100*(3+4)+18=10000-700+12=9300+12=9312

💖👌🏻

thank you very much this is so good I just didn't get the last one

Who else stop after he started multiplying higher than 11 ? 😂

Bro we need you hard!!!!!!! Thank you many times! Make more vids about calculating fast please!!!! ❤ Also how to solve algebraic problems, geometry problems fast and easily pls pls!!! That will help a lot for all of us, may Allah bless you😊😊

Damn!

Amazing video! I am also bangladeshi 🇧🇩🇧🇩
