If you're like me and haven't done any Algebra since leaving highschool (for me that was 15 years ago) this book is a excellent refresher course. The authors have use a conversational style in presenting the concepts of Algebra. Reinstalling your basic knowledge of math before you became tied to a calculator and guiding you through Algebraic methods and then backing those up with lots of examples and problems which really helps illustrate each concept. There is also a self-test at the end of every chapter.I'd forgotten most if not all the Algebra I was taught at school but this book has re-awaking the geek in me and made Algebra (dare I say it) enjoyable and not a not a teeth renching experince I'd invisioned.
