Introduction to Number Theory

The authors of this classroom-tested, student-friendly text illustrate the connections between number theory and other areas of mathematics, including algebra, analysis, and combinatorics. They also describe applications of number theory to real-world problems such as congruences in the ISBN system, modular arithmetic, and Euler’s theorem in RSA encryption and quadratic residues in the construction of tournaments. The book interweaves the theoretical development of the material with MathematicaR and Maple? calculations, while giving brief tutorials on the software in the appendices.

Tony Vazzana and David Garth are professors of mathematics at Truman State University.
