Key features of Number Theory: Structures, Examples, and Problems:

• A rigorous exposition starts with the natural numbers and the basics.
• Important concepts are presented with an example, which may also emphasize an application. The exposition moves systematically and intuitively to uncover deeper properties.
• Topics include divisibility, unique factorization, modular arithmetic and the Chinese Remainder Theorem, Diophantine equations, quadratic residues, binomial coefficients, Fermat and Mersenne primes and other special numbers, and special sequences. Sections on mathematical induction and the pigeonhole principle, as well as a discussion of other number systems are covered.
• Unique exercises reinforce and motivate the reader, with selected solutions to some of the problems.
• Glossary, bibliography, and comprehensive index round out the text.
