This book is really a great help for those wanting to exercise their math skills or even challenging themselves in precalculus. It provides answers in the back of the book so you can check your problems and in the beginning of the book it has some review chapters on basic algebra. I use it for my college precalc class it really does help and explains mathematics beautifully.

Sorry it took so long to get back to you. Your service was first rate and the book was delivered in a very reasonable amount of time. The book was in excellent condition for the price I paid, about half of new.

The author gives you lots of practice problems and because I bought the "instructors" edition I got the answers to all of the problems. I find it helpful when learning math, if you're having trouble, to look at the answer and "reverse engineer" the problem. Sometimes doing it this way, in combination with the examples, will give you clues as to how you should work the problem. If the answer that you are headed towards does not look like the answer in the book, you can analyze your work and figure out what you are supposed to do.

If you are someone like me who has not taken a math course for a few years, or if you have always had trouble with higher math like I have, you would be well served to refer to a book from an earlier level of math for additional help, such as my old Algebra 2 book. (I always keep my old math books.)

The author tends to use a lot of shortcuts without explaining that he has done so. If a user of this book, is not proficient in math this can serve to confuse and frustrate the user.

The CD, while it does have lots of good practice problems and the practice test routines are cool, has little in the way of examples. I really don't see the sense in having so many practice problems on the CD when the book itself is crammed full of practice problems. I think the CD would have been better if it explained more of the actual problems from the book.

The last two math books I used had, "CD" or "video tape" icons beside some of the problems that indicated that the problem was worked out on the CD. The "precalc" had no CD problems from the book and only a handful of "video tape" problems.

The item was misrepresented by the seller and when I contacted him/her, he/she did not reply....

One of the best online shopping experiences I've ever had. I placed an order and the book was at my home in 1 week in the condition listed. I will definitely look to buy from this person again!

This and the student guide have enough errors in the solutions that it'll have you questioning your work. Thank goodness for a patient professor (and I'm an A student). The sections don't cover very well the material in the questions at the end of the chapter. It is written a little better than the Algebra book by the same authors but if this can be avoided, avoid it. My own professor doesnt teach out of it, just assigns work from the end of the chapters...thats how bad it is.

I have never used the CD, but the book is okay. If you are going to take calculus in the future than you should get a cheaper precalculus book and save some money. This is essentially the same as the 4th edition, except the price tag. Only get if you absolutely must for a class.

This product was everything that it promised to be. I will continue to order from amazon.
