Can you mentally multiply enormous numbers faster than a calculator? Memorize a 100 digit number? Figure the day of the week of anyone's birthday? These are just some of the many feats of mind that will be demonstrated at this event. Mathematics can be a difficult and perhaps puzzling subject for many. But watch in amazement as one of the world's fastest human calculators shows his ability to turn math into magic.

Arthur Benjamin, Ph.D. is a professor of Mathematics at Harvey Mudd College in Claremont, CA. He is the author of Secrets of Mental Math and Proofs that Really Count as well as co-editor of the journal Math Horizons. Fusing his love of both mathematics and magic, he has appeared at the World Science Festival in New York and the Magic Castle in Hollywood. Reader's Digest calls him "America's Best Math Whiz".

  • This is time well spent. This is just amazing..... I want his brain too. That would help me a lot!! :D

  • Excellent....

  • i'm surprised that he's not asian

  • Lol I know how he does the guessing the missing number trick.. He had trouble with the last one because you can't tell if it's 0 or 9.

  • @CumCuBer that's not mathematics, that's arithmetic, if you know to multiply some big numbers in your head doesn't mean you know mathematics

  • the only thing I know is most of the people who're good at math are weirdos.... sorry. :p

  • Like a boss

  • @Ryushihotshot In a sarcastic way.... u know

  • @TheMasterThingMaker ... That's the amazing part?

  • The number of views lacks a zero at the end.
