In conducting a mathematical column in the Graham Dial over the past twenty-five years, the author found that the most stimulating experience and the greatest reward for his effort came from the "surprise attack" initiated by readers in solving many of the problems.
Mathematical Puzzles, for Beginners and Enthusiasts
This is a delightful collection of head-scratchers all described in an easy-going format. Puzzles (all of them are word puzzles, and all answers appear at the back) are grouped as algebraic, geometric, easy-arithmetical, combinatoric, puzzles about integers, etc.; none are trivial, some are extremely challenging, and they all teach some point about inference or mathematical method. In the preface, the author writes, "Some of these puzzles are old favorites...
There is little that I need say by way of introduction to this collection of puzzles. They are all strictly "mathematical," though the mathematical knowledge necessary for solving them is, in all but a handful of cases, elementary.
Following the content of the standard school curriculum, this book presents in 418 problems and diversions the basic ideas of arithmetic. Averages, fractions, decimals, percent, powers and roots, etc. Shortcuts, checking methods, also introduced in this enjoyable format. 120 illustrations.
Challenge yourself with over 100 fresh paradoxes, puzzles, riddles, conundrums, word and number games for the jaded, skeptical puzzlist. Over 100 pages of comprehensive answers. Approximately 300 illustrations. "Excellent collection of unusual, offbeat, and completely original puzzles."—Scientific American.
