I'm a graduate student in psychology and I need to learn some math fairly quickly for my studies. So not being a "dummy", I decided to leave the "guide" to the idiots and buy a book to "demystify" concepts I learned long ago, and teach me new ones I have not yet come across. The book has been great so far and is worth the buy!

The book is written for a college course, but it does not really cover thing taught there. It is a good book for review if you took it in high school, but not college Pre-Calculus.

This book is decent, but I found a couple omissions of important information. This required me to go online for explanations from alternate sources to fill in the missing info. Puzzling why this is so.

I am a teacher and have just moved to another state. I am tutoring a pre-calculus student who needes an "accessible" text to augment his textbook. The company from which I ordered this product had such a quick turn-around that I was able to deliver the book to my student within a week. This was a big relief, and I was quite impressed.

Books with titles such as X "Made Easy" or X "Demystified" should always be treated with caution and suspicion. And this is one of them. I have worked through Algebra Demystified and was pleasently surprised - but this volume did justify its title. Thinking that the same author would do something along the same lines with Precalculus Demystified - I was very disappointed. I'm not a complete dunderhead in maths but I did expect somewhat more of an explanation at each step. A word or two of WHY so-and-so is done in precalculus would not have gone amiss. This book is just another maths book with next to no explanation - just examples and problems. Some graphical illustration, for example, in Chapter 4 would have been enormously helpful. My volume is going cheap on Amazon second hand market.
