W. W. Sawyer was one of the greatest teachers of mathematics within the past century. The continuing popularity (to the extent that books on math can be popular) of his other books -- *Prelude to Mathematics* (which deals with advanced math) and *Vision in Elementary Mathematics* (which deals with arithmetic and basic algebra) -- serve as evidence for the wonderful ability he had to make math seem useful and interesting to everyone from the math-phobic to the dedicated mathematician.

Contrary to some other reviews, Sawyer's prose was NOT dull or dry. We have to keep in mind the fact that *Mathematician's Delight* was written for an audience in the 1940's to 1950's Britain and Canada. Obviously, the style and tone won't be consistent with the way that we 21st century Americans are used to. But even giving him that benefit of the doubt, Sawyer's prose is always lively, entertaining, and full of insights into his chosen subject of mathematics as well as insight into why many people struggle with aspects of that subject.

I definitely agree with the positive aspects of the other reviews. This indeed is an excellent book to take you from the basics of algebra all the way up to and beyond calculus. I sincerely hope that someone brings this book back in print.
