An introductory course in number theory for those taking a mathematics major. It contains graded exercise sets, as well as clear explanations of number theory with special emphasis on creating and understanding proofs.

This book is intended for an introductory course in number theory, primarily taken by mathematics majors. The author wrote the text with four main goals in mind. He wrote a book that is both easy to read and easy to teach from. The author also aims to ease students into using proofs, and to develop a self-confidence in mathematics surrounding the difficulty of mathematical proof. Although the main users of this text will be mathematics students, a large audience could easily use the book.
