Series: Problem Books

This collection includes 100 problems in the areas of arithmetic, geometry, algebra, calculus, probability, number theory, and combinatorics. The problems start out easy and generally get more difficult as you progress through the book. A few solutions require the use of a computer. An important feature of the book is the bonus discussion of related mathematics that follows the solution of each problem.

In mathematics there are problems that, while sounding difficult at first, have beautiful, elegant, and most notably simple solutions. Oftentimes when approaching such a problem, many minutes, hours or days will go by before stumbling upon the simple solution. All at once, things align, and your mind screams “Aha!” *Aha Solutions* is a well thought out compilation of these unique and interesting problems. Continued...
