Math Tricks

Book excerpt: It is no secret that most people avoid mathematics, in large measure because elementary school teachers have never done much to motivate a love of the subject matter. In his latest book, mathematician Alfred S. Posamentier provides easily understandable, easily presentable and easily replicated tricks that one can do with mathematics. All that is required is the ability to do arithmetic, understand the very basics of algebra and geometry and have an open mind for probability. From geometrical puzzles to numerical quirks, Math Tricks will give readers that "aha!" moment they may never have received at school.
