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 -

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)

IBM's Watson / Big Blue can interpret language and perform the calculation faster than any human now
Wow, his brain must have lots of numbers and he probably is not forgetfulll like me. He did it well and correct. I calculate it to make sure it is correct.

Roger Wang
I wanted the audience members to troll him and say easy numbers like 10 or 100 :(
Ridwan Khan
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.
Stubby the orange
Those wth the calculators are doing that faster than humanly possible. That's why I don't beleive any of this

He's faster than people typing out numbers on a calculator. Definitely not faster THAN a calculator (Which is nearly impossible to do). Still very impressive.
