I'm all-for electronic textbooks, but whatever system was used to perform the document master to Kindle edition conversion did a really lousy job. All of the more complex elements (variable names, equations, etc...) are represented using ultra-low resolution, distorted graphics. Blurry at best, illegible at worst. Some of the elements are missing altogether, such as the minus sign on the very _FIRST_ page!

Did anyone actually proof the text once it was converted?!

The publisher must have corrected the issues that the previous reviewers wrote about. I downloaded this in May, 2011, and it does have a table of contents and the graphics are fine. I think it's easier to read on my PC for Kindle than on the kindle itself because of the nature of the textbook, but even on my kindle the graphics were clear.

I hadn't even considered downloading this because of the negative reviews, but decided to try it since it's free anyway. I'm glad I did. I'm very pleased with this book.

I can not complain much about a free book, I wanted it as a refresher of algebraic principles. The text seems to be okay, but so far, half way through the first chapter, I have encountered a number of problems with, well, the problems. A variable is listed in the practice section as squared, but when checking the answer it is apparent that it was cubed instead. A plus sign is switched for a minus sign, a number is changed. It does make doing the practice annoying. However, I am still learning and remembering about algebra.

I was skeptical based on the other reviews of this book, but I'm able to view the book just fine on my Kindle 3rd edition and the desktop software. If you're looking on brushing up on algebra or even help with homeschooling or tutoring algebra, this is a great book for the price (since it's free.) It's even worth downloading if you don't own a Kindle (you could use the desktop client) and use this as an extra resource.

Like any math textbooks, there are errors. Having taken a great number of math classes over the course of my life, I'm not phased by it, but I would hope that it's corrected in a future version of the text if you were going to use this as an educational resource.

I don't usually write reviews very often, but I wanted to save people the time and frustration of even downloading this free kindle book. It is terrible! I love the idea of having a textbook on kindle, it is an amazing way to learn, however, the math problems in this book are completely wrong. You will see problems that say X^2 however the answer they give to the problem will not be X squared, it will be X cubed. This is very frustrating and would easily confuse someone who is new to algebra. These errors are thoughout the book!

There are other books in the CK-12 series that are much better, but the Algebra I book is not even worth $0.00

I am very BAD at anything more than basic algebra. So when I found out that this was free I was very excited. It explained things quite clearly and simply and seemed built for people like me who have trouble with math.

Now I see why Feinman was screaming while reviewing text books. Some equations have + signs were an = sign is supposed to be.
Some make no sense at all. The editor must have red the book while asleep or was not familiar with grammer or tense. This would be a good book it didn't frustrate young readers who may spend a considerable amount of time trying to figure out how an answer or progression was derived only to discover they were unduly taxed by printing or mathematical or other errors.
I suggest scowering the Internet for a book which the writer and editor were attentive. Otherwise (no comma on a kindle) prepare to buy a lot of Rogain.

I admire the publishers for attempting to create a free textbook, but it looks more like a error-ridden rough draft than a final draft. There is at least one math typo every page (not counting the grammatical errors). Sometimes it is simply a sign change error, but frequently the writer gives a problem, then changes the original problem when offering his/her solution. 2x+5=8 suddenly becomes 2x+6=8. Worse than that were all the times he or she forgot the original problem halfway though solving it. Also, perhaps fifty images were broken/missing in the text.

Since I'm just reviewing all my previous math from algebra to calculus, it suited my purposes. However, do not under any circumstances use this book to learn algebra. If you have a really solid foundation and just want a quick review before you move on to other things, then it's okay for that (and for a chuckle if you don't rip your hair out first). I've gone through the geometry one as well, and it's just as bad (without the broken/missing image problem).
