I used this textbook last year for my Algebra II class. I personally loved this book. It had very good, worked-examples in each section that were exactly the same as the practice problems given. Most textbooks start out with some information explaining what is going on, and then the student is just supposed to put the pieces together on how to do the problems, whereas the examples in this book show the student exactly how to do the problems. My algebra teacher was not very good, and while she did work out examples on the board for the class, they just never made sense. By the end of the year, I stopped even listening to her lessons and I just did the problems in the book on my own. I made an A in the class, and even though math is one of my weaker subjects, I think I learned enuogh to do fine on the SAT and ACT.
However, my teacher disliked this book. She said that it really needed to include more graphing, and that it was outdated.
To each his own, I guess. I definitely think that its many clearly layed out examples helped me.
