Overview
Elementary Number Theory helps you push your understanding to new heights with the strongest exercise sets, proofs and examples. Applications are integrated throughout. Connections with abstract algebra help those who have already studied it, and lay the groundwork to understand key ideas if you're taking abstract algebra in the future. Computational exercises and computer projects are available for Maple, Mathematica, Sage Math and the book's many online resources.
The 7th Edition offers a presentation that's easier to learn from, while incorporating advancements and recent discoveries in number theory. Expanded coverage of cryptography includes elliptic curve photography; the important notion of homomorphic encryption is introduced, and coverage of knapsack ciphers has been removed. Several hundred new exercises enhance the text's exercise sets.
