Arthur Benjamin on "Becoming Mathemagician"

[@anjalivats287]

That happiness on his face while teaching something he loves. That's extremely beautiful.

[@minetime6881]

He really is very happy when teaching lol

[@rhm5158]

Looks like he is one fantastic teacher. Amazing enthusiasm

[@tawseefahmad1131]

Respect Sir... From INDIA.

[@joppadoni]

An amazing educator. Love the Art.

This Professor is a Master of Arithmetic :)

[@joppadoni]

mental arithmetic, as well as maths, generally.

I am from Britain, Wales to be exact and I am a 25 year old man and I just wished I had a Maths teacher like Arthur Benjamin. He explains Maths in a way that it is like "wow I understand that" or "wow there is a little trick in there". The Maths teacher I had in school, well he wasn't a nice man to say the least and it made me hate Maths.

[@brishneeluximon784]

I just love him He teaches soooo well Well done sir♡♡♡

[@aclemasultan1794]

Why are some people are hating him ?

Good man. I use your videos in my tutoring, kids love it.

[@irfanhanief1147]

Im gonna watch all of your videos

Sir You are legend

[@nithikasamadith3440]

my respects for teaching this this easy methods to us.

[@rootsofdisunity3414]

This property is an application of the difference of two squares formula. So given a number 2n, for some positive integer n, n + n = 2n and n*n = n^2. (n-1) + (n+1) = 2n and (n-1)*(n+1) = (n^2) - 1. And (n-2)*(n+2) is (n^2)-4 so on and so forth. So these relatively boring formulas we learn in school are actually brought up as really cool patterns. Also his method where he does 13^2 as 16*10 is another extension of this. So 16 is 13 + 3 and 10 is 13 - 3 so (13 + 3)(13 - 3) is 13^2 - 9, or 160. Mr. Benjamin just reversed this sequence to get 13^2 easily, as 16*10 is easier to calculate.

[@Corazonlatino1995]

You are wrong, because necessary 13² need to end with the digit 9 because 3*3=9, and so the right formula were 16*10+ 3²* = 160+9= *169*. 🤷‍♂️🤷‍♂️. Another way(little bit more long) were to do (13-8)(13+8)+8²=5*21+8²=105+64= *169* !! They are many ways to go to ROMA!! 💪🤙🤣

[@eplaneteducationplanet]

Thanks for this incredible method of the square, you are so great mathmagician, Can I get other videos to learn some new topics of maths with the easy method as your discovered. I have seen your calendar method also, but I am expecting some new videos with some others topics. Thanks.

[@jaisonphillip8017]

Thank you Sir

Watch Art Benjamin ( Harvey Mudd College) describe a childhood experience in which he discovered a trick for mentally calculating squares, leading him to a career that combines mathematics and magic.

[@kevinhariya5591]

Thats not magic. That's VEDIC MATHS

[@akhtar7574]

This man is good! (^^,)

[@markracadio6902]

This person is unbelievable i wonder why he has dislike on this video. This method is long overdue and educators cant appreciate this. Some tutorial schools knew this just saying by the way.

[@quinna.1072]

Very cool.

Make first toilet then give congrats

[@nightfallchronicles121]

Any body help me in finding 72×72 using this method i think it isnt working

[@paredeschris6209]

It does work 72 you move 2 down and 2 up in that case you multiply 70 and 74 and you get 5180 and then add the square of 2 which is 4 then you get 5184

[@nightfallchronicles121]

How do u multiply 74 with 70 the easy way please tell

[@paredeschris6209]

It's because of the 0 you can do it like this 74 times 7 you get 518 then you can just put 0 in the end so you get 5180

Maybe I will be like him when i'll be older, I mean at the age of 8, I was discovering the same thing (a+b)(a-b) = a²-b²

He is not mathemagiician. He all showed up is VEDIC MATHS

[@kevinhariya5591]

Just read my comment which i posted in comment section about vedic maths

[@deanarond8889]

I am better than him. I wrote him an email, and of course he ignored me! That does that make him a coward? Inspired by him, I squared my first 5-digit number on December 31, 2015. I am currently squaring 7-digit numbers, and look forward to trying 8-digit numbers soon. The trick he discovered at 13 years old, I figured out in 15 minutes at the age of 8!!

[@diegomunoz2695]

Sure, mathematicians spend their time squaring 8-digit numbers.you will win a Fields Medal soon.

[@lightspeed2014]

If your so good, why aren't you famous yet, that guy became famous because he had talent, and I don't think that I've seen the name dean around anywhere in the field of mathematics

[@aperson7427]

Stop getting so salty

[@kevinhariya5591]

You are not a mathemagiician!! You showed the tricks of mathematics which ancient INDIAN Sadhus( Sages), Gurus( teacher) and Indian mathematician used during and after the VEDIC PERIOD. And this maths later came to be known as VEDIC MATHS. Which you showed as magic maths. You can too search the web for the same

[@aclemasultan1794]

Arthur Benjamin is a professional magician and performs his mixture of math and magic which is why he doesn't call vedic math and he is famous.

[@aclemasultan1794]

But ok.
