Elementary Number Theory, 7th Edition

Elementary Number Theory helps you push your understanding to new heights with the strongest exercise sets, proofs and examples.\n\nApplications 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.Elementary Number Theory 7th Edition is written by Kenneth H. Rosen and published by Pearson.
