I am a do it yourselfer, pull yourself up by the bootstraps kind of guy. So I am very familiar with these types of publications. I think this is one of the best I've ever come across. From the pretest to determine how much algebra you retained to the final chapter of solving systems of inequalities and linear programming, this book is easy to follow, very explanatory and not redundant. I highly recommend it.

This book contains several errors. It is unsuitable as a refresher and COMPLETELY unsuitable as a self-teaching guide. I suggest "Trigonometry Refresher" by A. Albert Klaf.
By Chemical Emma (Medford, MA United States)
If the purpose of instructional books is to build a foundation of knowledge in a subject, this one fails. The concepts are presented in a relatively straightforward fashion, but there really aren't enough problems to enable the reader to master those concepts. As many other reviewers have noted, the book is riddled with errors, including some arithmetic errors that are so painfully basic that the authors should be embarrassed to have their names attached to the finished product - and those are just the ones I noticed; I'm sure someone who really knows their precalculus could find dozens more. If I wasn't already fairly comfortable with math, the errors in this book would seriously undermine my confidence in my skills; as it is, they just undermine my confidence in the authors' skills.

Breifly - there are errata in even the 'Basics' section at the beginning of the book, which is the elementary algebra review.
The cover of the book boasts, "Over two million copies sold". Well, if that's the case, then there has been over $35.9 million dollars wasted by trusting consumers (at $17.95 retail). I invite the lazy editor of this book to check my math.

I was bothered by the review written by Antonios Giannakas. Mr. Giannakas calls himself a mathematician, I am not convinced he ever read the book. If I (an undergrad.) can find numerous mistakes in this math text, a MATHEMATICIAN should be appalled by the amount of incorrect information in this book. It is hard to believe this book was ever published in the first place. STAY AWAY FROM THIS BOOK!
