I bought this book as a supplemental study guide - my course was a mix of Number Theory, Abstact Algebra, Finite Fields and Probablility (pre-requisites for Cryptography study). The professor used lectures with hand-written supplements as primary study media.

I found this text to be well-written, each concept was dealt with separately and concisely, then later assimilated with others to form broader ideas. Even though the text is directed at Number Theory, many of the other related concepts I studied were mentioned or covered in this text.

This book will stay on my bookshelf for quite a while.

This books gives an excellent background to elementary number theory. I've found this book gives lots of examples, theorems that are helpful with interesting excercises. What I do find frustrating is that here and there the methods given are innefficient compared to what my proffesor teaches in class. As well some of the proofs are written as one giant run on sentance, and written line by line. This is VERY hard on the eyes and totally annoys me.

I'm impressed with how modern and interesting this book makes number theory seem. I've always liked this subject, but I've found the other texts out either too old-fashioned, boring, or too sophisticated. This book hits the mark. Highly recommended for the number theory enthusiast like me!

I'm currently taking a Discrete Mathematics class that is a stew of number theory, abstract algebra and probability.

This books has been very helpful as a reference as my professor teaches the course from his own lecture materials that often do not provide enough examples or coherent explanations.

The chapters on cryptography add a welcome flavor to the material.

The book starts out as though you were a Freshman or a Sophomore, when your not. It's been about 17 years since I had fun with "Linear Algebra". A -fun- read for a nerd, I guess, or others that enjoy Mathematical expantion.
