Here’s a TED talk by Arthur Benjamin showing Mathemagic Faster than a calculator | TEDxOxford
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.

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)
