*School Math Fundamentals* provides a look at many of the algorithms present in pre-calculus mathematics. The book consists of a treatment of the mathematical topics of multiplication and division; basic operations; proportion; quadratic equations; trigonometric and inverse trigonometric functions; the Pythagorean Theorem and the Law of Cosines; and exponential and logarithmic functions. Each topic is given a separate chapter. Each chapter contains a brief discussion of the topic, occasionally accompanied by figures, along with definitions, examples and some proofs.

The treatment of topics is mostly algorithmic. For example, the discussion of division of rational numbers uses a numerical example to demonstrate that the algorithm for division of rational numbers *p _{1}* and

A few issues are handled unsatisfactorily. In the chapter on basic operations, the discussion of the multiplication algorithm refers to “adding a zero” to the right hand position of a number when multiplying by ten. While this is common English usage, a mathematical text should be more precise about its use of mathematical language. “Appending a zero” would be a simple change that would improve the clarity of this discussion of the algorithm for multiplication of a whole number by ten. Secondly, the discussion of exponential functions uses limit notation and concepts without addressing the concept of limit. This is not atypical of pre-calculus treatments of limit topics, and yet a book that claims simple explanations of school mathematics would be improved by more attention to this concept than referring to a limit using the vague language of “approaching.”

This book is presumably aimed at successful mathematics undergraduates who know the algorithms of high school mathematics and want a second look at them. Such students will likely appreciate the discussion of multiplication of negative numbers. The book does not offer many concrete explanations, making it unsuitable for those who want conceptual understanding rather than symbolic.
