Ross Honsberger has done it again. He has brought together another wonderful collection of elementary mathematical problems and their solutions abounding in striking surprises and brilliant ideas that reflect the beauty of mathematics. Many of these problems come from mathematical journals. Others come from various mathematical competitions such as the Tournament of the Towns, the Balkan Olympiad, the American Invitational Mathematics Exam, and the Putnam exam. And, of course, there is a problem suggested by Paul Erdos. This book is ideal for students, teachers and anyone interested in recreational mathematics.

Choice Review

Honsberger offers a nice group of math problems intended for anyone entertained by solving challenging problems. The problems were collected from sources such as the Tournament of the Towns, the Putnam Mathematical Competition, the Canadian Open Mathematical Challenge, the American Invitational Mathematics Exam, and the 1990 Balkan Olympiad, along with many others. Two chapters are based on work by legendary mathematician Paul Erdos. Topics range from Euclidean geometry to number theory, and treat such problems as stacking wine bottles and the coin-matching game. Each section of the book is independent, and thus the book can be read in any order. Written in a relaxed fashion, it is truly a fun and fascinating book for any mathematical mind. ^BSumming Up: Recommended. Lower-division undergraduates through professionals. M. D.
