Mathematical Magic by William Simon

Mathematical Magic is exactly what its name implies – entertaining tricks, stunts, and effects that can be performed using numbers or objects, such as calendars and playing cards based on numerical principles. These tricks are amazingly simple and require only a few additional props, such as string, coins, or matches, nothing elaborate or professional. With a little practice and some patter, any amateur can put on a performance like a real professional.

The fascinating properties of numbers and the strange coincidences connected with them have been the subject of many books, and mathematical puzzles in endless variety are an inexhaustible source of amusement to everyone who likes brain-twisters. This ebook goes a step beyond such puzzles by using numerical peculiarities for ingenious and baffling entertainment.
