Erickson provides 100 exemplary problems to whet any problem-solver's appetite....A bonus is Erickson's detailed discussion of an AHA solution to each problem followed by discussion fo related problems and mathematics. --J. Johnson, CHOICE Magazine
Erickson collected 100 problems from different areas of mathematics, and as one progresses in the text, they go from elementary to advanced. A short "toolkit" of ten pages at the end recalls some of the definitions and very elementary mathematics that are needed. The number 100 is actually an understatement because almost all of the problems come with a "bonus" that gives background, but also variations and extensions of the basic problem that is tackled.
The number theoretic examples are of course easy to understand for anyone, but there are also problems from calculus, probability, combinatorics, and geometry. They are all easy to understand with only little or no mathematical knowledge. The solutions however are sometimes much more demanding on that part. A computer is rarely needed. The formulation of the problem (often one or two lines) is immediately followed by the solution. This is fortunate for readers who get easily addicted to puzzles, because if problems and solutions were in different sections, you could get hooked in trying to solve the puzzles by yourself. It is an excellent advertisement for the fun and the beauty of mathematics. --Bulletin of the Belgian Mathematical Society
Mathematicians (beginner, amateur, and professional alike) thrill to find simple, elegant solutions to seemingly difficult problems. Such happy resolutions are called 'aha! solutions,' a phrase popularized by mathematics and science writer Martin Gardner. Aha! solutions reveal the beauty of mathematics. This book is a collection of problems with aha! solutions.
