Benjamin makes numbers dance. In his day job, he's a professor of mathematics at Harvey Mudd College; in his other day job, he's a "Mathemagician," taking the stage to perform high-speed mental calculations, memorisations and other astounding mathematic stunts. It's part of his drive to teach math and mental agility in interesting ways, following in the footsteps of such heroes as Martin Gardner.

TEDxOxford is organised by University of Oxford students, aiming to bring together the young minds of tomorrow's world with the movers and shakers of today. TEDxOxford is kindly sponsored by Neptune Investment Management - www.neptunefunds.com

In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)

R Kसाल पहले^{+4}The calculators deserve a round of applause for calculating as fast as him.

𓈗 𓇡 𓇢 You tube 𓆓2 साल पहले^{+1}Its not talent,

SPSheepसाल पहले^{+3}"Does anyone have a calculator?"

am45in46 XDसाल पहले^{+3}And then there is me who is typing 10+15 on my calculator during my math exam bc I have trust issues

Mathijs Arendसाल पहले^{+724}For those wondering, at

Kingसाल पहले^{+1}he wrote a book explaining his tricks. that book served me well back in high school

Bradley4ever3 साल पहले^{+24}All of the dislikes were calculator manufacturers.

[GD] Slapp2 साल पहले^{+1}Teacher: get your calculators out!

wrh152साल पहले^{+343}I loved the "Light, Tomorrow" moment to describe 51,134, because he is uses the same memory trick my father taught me as a 10 year old in 1980 to remember card sequences. It is really useful and anyone can learn it. When he says he's "storing numbers" in a "phonetic code", he means he is comitting the number to an image (made of words) and when he wants to recall the number he just reaches for the words and (if you know the trick) you can reconvert the words to the number. The sequence he is using is the classic "peg sequence" from Harry Lorayne: Tie = 1, Noah = 2, Ma = 3, Rye = 4, Law = 5 etc. So Light = 5 and 1 (L and T), and Tomorrow is the 1 and 3 and 4 (T and M and R).

͔साल पहले^{+7}Asian parents:

Foarestसाल पहले^{+991}he just memorized every possible equation ever. It's that simple.

JG^{+82}I like how he takes more time saying the answer than he does solving the problem

Bombour3 साल पहले^{+3}I hope he had lots of kids for the sake of humanity.

Daniel Adeyinka2 साल पहले^{+2}"I would attempt to square a five digit number, and I can...but unfortunately most calculators can not". Omg 🤣🤣

Purple Rickसाल पहले^{+1}He : does multiplications within seconds

Amiin A. Aidid^{+3}This is not easy. He worked his whole career on it. Made researches and had all those sleepless nights thinking of them. Everything the person puts an effort on, becomes this wholesome.

sirius black7साल पहले^{+67}The fact that he can instantly run through tons of numbers in his head to get the answer literally blows my mind and I can not even begin to comprehend how his brain possibly does it

Serwan Sheran21 दिन पहले^{+2}I hope I had this teacher in my primary school! I would love mathematics! Great practice and amazing teaching !

Radiated Leader2 साल पहले^{+2}Teacher: "you won't always have a calculator on you"

Arthur Cooperman2 साल पहले^{+13}I love how he makes the audience give the dudes with calculators on stage a round of applause for doing what he did in one second in his head
