I am currently entered as a freshman in college and we are required to use the book. This book helps you show how to work out the problems in the best way possible. They should continue using this book for years to come.

This book was the textbook when I took my first course in Number Theory many years ago. At that time I found it to be very easy to read and the exercises challenging, yet doable. Since then I have used it as my first reference when encountering any problem in number theory where the background of the problem does not immediately leap to mind. In previous years, I used it as a resource in solving many problems that appeared in problem columns. Nowadays, I use it in my capacity as the editor of Journal of Recreational Mathematics when I am evaluating papers for publication. Even though I have many other basic number theory books in my library, it has stood the test of time, never having been bumped from the privileged position on my bookshelf.

The book explains the material in sufficient details and supports it with easy to understand examples. Also, the exercises and assignments are of appropriate level of difficulty. Overall, I think the authors have done a great job.

Bad Book on an already hard subject. There are better books out there. Don't waste your money or time on this stinker. It left me dazed and confused. It didn't teach the subject just gave examples which would be fine, if the examples were based on the exercise problems. What a waste of paper.

This was a horrible text book. It does not help with teaching, or with explaining the topic at hand. Instead it gives examples,which would be fine except the examples were not like the exercise problems. The book left me confused, and with plenty of questions for my instructor. I hated this book, and looked for better books to get me through the class. Alot of money for nothing. There are better books out there.

The book itself is OK at best. The author makes use of OK examples but has some very good questions. Too bad its hard to solve the more advanced questions he asks from the examples given.

In compairing the 7th and 8th editions there is almost NO difference between the two. I think I ran accross under 10( at most) total changes, and they were VERY minor. Why print another edition? More money to charge university students is probably why.

Oh, and I did very well in the 2 semesters...so Im not just bitching either!

This little pamphlet is only 45 pages long and costs sixty dollars. It just has some screen shots and is very simplistic. Save your money!
