Arthur Benjamin and his Amazing Mathemagic

Here is an interesting video of mathemagician Arthur Benjamin races a team of calculators to figure out 3-digit squares, solves another massive mental equation and guesses a few birthdays. He tries to show you how he does it at the end, but I still can't imagine being capable of replicating the amazing feats he pulls off.
