Since many problems do not require advanced knowledge of mathematics, the text appeals to a very wide audience of mathematics fans. Challenging and inspiring problems in this collection will help to develop reader's mathematical skills, stimulate creative thinking, and promote further interest to the subject." - Zentralblatt Math "This book is an enormous storehouse of problems that middle school ... Read moremath teachers can use in their classes. Most of the problems are what could be categorized as 'fun' and the solution of many requires nothing more than simple persistence rather than significant mathematical insight. People that home-school will also find it very valuable in presenting challenging problems to their students. These are also great problems for classes designed to teach future elementary and middle school math teachers. Even mathematical veterans will find the mathematical components of their brains challenged a bit as they read through these problems." - Charles Ashbacher, MAA Reviews Show Less
