Scientific Technology:Arthur Benjamin Does Mathemagic
Arthur Benjamin is a "mathemagician". In this program, he will combine his loves of math and magic to do something he calls "mathemagics". There is something called the square of a number. It is taking a number and multiplying it by itself. What Artjur is going to try and do is to square, in his head, four two-digit numbers faster than others can do on their calculators, even using the shortcut method.
