Elementary Number Theory and Its Applications – Bart Goddard, Kenneth H. Rosen – 5th Edition


Elementary and Its Applications is noted for its outstanding exercise sets, basic exercises, exercises designed to help explore key concepts, and challenging exercises. exercises and projects are also provided. In addition to years of use and professor feedback, the fifth edition of this text has been thoroughly checked to ensure the quality and accuracy of the mathematical content and the exercises.

The blending of classical theory with modern applications is a hallmark feature of the text. The Fifth Edition builds on this with new examples and exercises, additional applications and increased cryptology coverage. The author devotes a great deal of attention to making this new edition up-to-date, incorporating new results and discoveries in number theory made in the past few years.
