Arthur Benjamin does "Mathemagic"

Arthur Benjamin is an absolutely phenomenal mathetician. He starts off his talk by squaring any two digit numbers, then three digits, then four digits. He then is able to determine the number that is left out of a seven digit number which is the product of a certain number and any random nuber. Then Benjamin rattles off the day of any date in any year. Such as August 12th 1923 was a.....? Sunday! It was crazy awesome. He then concludes his show by squaring a FIVE digit number. He does the process out loud so we can hear what is going on in his mind while he is doing this. He says that he breaks up the problem into three different parts and also has certain words to represent certain numbers. In this case he uses fishen and cookies as representations of some number that I am unable to determine. This man was fantastic and extremely entertaining.
