Elementary Number Theory (English, Gareth A. Jones)

A book that does what it says

I bought several other classics to start in number theory. They were recommended by the pros. I don't doubt these other books (like Hardy ...) are really good but the people recommending them don't have a clue what it means to be a novice in anything or they have long since forgotten.The "elementary number theory" on the other hand is really what it claims to be. The explanations are really good. So are the proofs. I like this book because it never claims something to be too obvious not to

very good introduction to number theory

Some reviewers have said it assumes almost no previous knowledge, but that's not entirely true. It does use an elementary approach, and assumes little knowledge of advanced mathematics from the reader, but if you are a neophyte in mathematics this is not the book, it is better to use a more elementary book to have more benefits.For the small size it has there is a lot inside it, and the writing style is pleasant, although, sometimes, important details are, in an undesirable way, left out.The fac

Buena introducción

Buena introducción sin perder el rigor matemático. Una buena lectura antes de empezar con otros más avanzados como el Hardy&Wright o el Rosen.

an true investment in mathematical knowledge

Which level is the book aimed?This book (i.m.h.o) is a carefully composed introduction to underpinning knowledge of Number Theory topics. Its true -as its stated in the book- that introductory parts may be 'A'-level, but this builds beyond this without becoming worrying or intimidating! After a several weeks of effort on my part, I have found this book both helpful and clarifying and worth the time studying it.I found this book layout enjoyable, progressive and interesting. Also its questions

Perfect for university or self study

I would just echo everything that the previous reviewers have said. I have used this for self study and have found it wonderfully clear. I also bought some Open University texts for a few more exercises on Diophantine equations and congruences, but really all of the key ideas are in the book.
