Fundamental Number Theory with Applications

I had the luxory of using this book, and also the great honor of being taught by the "great man" himself, who has written this 120 dollar peace of trash. The book is terrible, when trying to read through the proofs in each section, halfway through the proof it says "this part is left as an exercise" and an even excersise none the less, I mean if your gonna go through a proof make it COMPLETE, don't tell me its an easy exercise, thats BS, now thats the book, now ill leave you to imagine how terrible of a proffesor he was, let me just say this, i love mathematics, and im planning on concentrating in crpytography, but that SOB Mollin, has me reconsidering the hole thing all together, i'd rather quit the concentration than to have to even open that textbook again and sit through one of his lectures.

A very solid, rigorous introduction to its subject. Scads of exercises, which is utterly essential for you to gain fluency.

This book is a confusing mess. If your considering this for an introductory number theory course, stay away.
