The book has been great so far and is worth the buy. 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.
It is a good book for review if you took it in high school, but not college Pre-Calculus. The book is written for a college course, but it does not really cover thing taught there.
Puzzling why this is so. 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.
This was a big relief, and I was quite impressed. 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. 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.
I have worked through Algebra Demystified and was pleasently surprised - but this volume did justify its title. A word or two of WHY so-and-so is done in precalculus would not have gone amiss.
Some graphical illustration, for example, in Chapter 4 would have been enormously helpful. This book is just another maths book with next to no explanation - just examples and problems.
Books with titles such as X "Made Easy" or X "Demystified" should always be treated with caution and suspicion. I'm not a complete dunderhead in maths but I did expect somewhat more of an explanation at each step.
My volume is going cheap on Amazon second hand market. And this is one of them.
Thinking that the same author would do something along the same lines with Precalculus Demystified - I was very disappointed.
