Mathemania

by Raymond Blum, Jeff Sinclair (Illustrator)

Abracadabra and 1-2-3! Amaze your friends and stump your parents with mathematical magic tricks. You don't need magician's equipment to perfect each feat; just practice it a few times. Some will turn you into a mind for example, just ask an audience member to roll some dice and stack them. Then, voila! You'll conjure up the total numbers on the hidden dots and tell everyone. Or, guess a word someone has picked from a dictionary. Want to make a little "Pumpkin Pi?" ("Pi," in algebra, is what you get when you divide the circumference of a circular object by its diameter.) Here, no matter what number someone enters into a calculator, the result is always a "piece of pi." Plus : a little card sorcery, mind-boggling magical things you can do with paper, and many more.
