title: An Accompaniment to Higher Mathematics (Undergraduate Texts in Mathematics)
author:  George R. Exner 
description: Though I am neither a student nor an instructor of mathematics (although I use mathematics in my teaching and apply it in my work), I found this book extremely useful and fun to read. The language is colorful, the phrasing is simple, and the facts are not intimidating. At times, I felt that I was reading a good novel, whose characters were definitions, examples, rules, proofs, and such, and that I had a magic stick to make them behave according to my will. -- <i>T. Rus, <i>Computing Reviews,</i> May 1997</i>
