The Canadian journal Crux Mathematicorum has a devoted following among people interested in mathematics problem solving, especially mathematics competitions. A central figure over its thirty-year history is Murray Seymour Klamkin (1921 2004) who started the famous Olympiad Corners and edited it for many years. He is a regular contributor to the Problem Section as well, both composing new problems and solving those proposed by others.
This book is a collection of all of Murray s problems that have appeared in Crux Mathematicorum. It is a most valuable resource for anyone interested in problem solving and competitions. The problems are classified by subject, and the topics span the entire spectrum of the mathematical curriculum, from the very elementary to the most sophisticated. Often, multiple solutions are provided. Now and then, we get comments from Murray himself, providing additional insight to the problem under discussion.
Since the problems are largely independent of one another, it is not necessary to understand everything, which makes the book suitable reading at any level, from junior high school to graduate school. It is a very good way of exposing young readers to more advanced topics.
