In this undergraduate-level text, students are introduced to abstract mathematics and proof techniques. The text's clear, organized presentation pays special attention to how proofs are created, using many computational examples and problems. Extensive exercises and problem sets (over1,400), ranging from drills to harder proofs, will challenge students of all abilities. Broad coverage of historical material, from Euclid to Public key cryptography, includes biographies of important number theorists and reproductions of newspaper articles.
