Treasury of 135 bafflers (70 "quickies" and 65 "micropuzzles") specially designed for computer hobbyists. Puzzles range from relatively simple exercises in logic to daunting mathematical brainteasers. Although a computer is helpful, many can be solved with pocket calculator, pen-and-paper or just plain brain-power. Introduction. Answers.

Fifty unique brain-teasers requiring a minimum of mathematical skills challenge the reader's ability to reason logically

For the mathematics enthusiast of any age or level of sophisitcation, this stimulating treasury of unusual math problems offers unlimited opportunity for mind-biggling recreation. Carles W. Trigg, Dean Emeritus and Professor Emeritus at Los Angeles City College and one of the country's best-known problemists, has compiled nearly 300 mathematical brainteasers from the field of of arithmetic, algebra, plane and solid geometry, trigonometry, number theory, and such general recreational mathematics and dissections, cryptarithms and magic squares. The object of each problem is to find the quickest, most elegant solution - they are often unorthodox and there is usually and element of surprise in each. Ranging from the simple to complex, problems are both original with the author and the work of over 100 other qualified mathematicians. Most are rarely seen or entirely new; all challenge the reader to devise solutions more elegant than the ones provided.
