TED Conference speaker Authur Benjamin combines his love of Math and Magic into "Mathemagics" by performing lightening-fast calculations in his head against a panel from the audience armed with calculators. He can even calculate the day of the week you were born on!

The capper? He performs the square of a five-digit number out loud so that you can hear what goes on in his head while he's doing it. With his calculating wit, Math isn't all he's mastered; he's an entertaining performer as well.
