This book, divided in three parts, looks at elegant solutions to seemingly difficult problems in arithmetic, algebra, geometry, calculus, probability, number theory and combinatorics. The books contains 100 problems some of which are new and others not new but not well known either, and each problem is classified as elementary, intermediate or advanced depending on difficulty. Besides the solution, each problem also contains a `bonus' section which expands on the topic area by providing further investigative questions or more advanced background material. This extremely well written and easy to follow book concludes with a useful toolkit summarizing the main relevant theorems and terminology, a list of all the `bonus' material, an index and selected bibliography.
