Contents: This book uses brain-twisters and elementary mathematics to teach you how to solve all kinds of problems. Part I summarizes the methods and illustrates them with examples, giving step-by-step instructions on getting started, working out the details, and checking the answers. Part II contains one of the largest recreational problem collections ever compiled: over 600 problems, many never published before--everything from riddles to the risks in Russian roulette, suitable for classroom use or your own amusement. Part III gives solutions obtained via the techniques described in Part I, explaining how to use what you have learned to solve similar problems next time. The problems are illustrated and fully cross-referenced.
