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 - http://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)

I wanted the audience members to troll him and say easy numbers like 10 or 100 :(

I can do the same this as him but I haven't practiced much so I can't do big numbers. Mines are either single or double digit multiplication/ divisions.

Today, an officer came in and said as an example "I'm just slouching over here while the teacher asked what is 2+2? I'm over here think the right answer, 2+2=9." Very confidently, the guy next to me didn't make it better, he laughs weird, I'm trying not to die.
