Covers the topics considered in a first course in number theory. It is intended for those who may have seen the material before but have half-forgotten it, and also for those who may have misspent their youth by not having a course in number theory and who want to see what it is about without having to wade through a traditional text.

Underwood Dudley was born in New York City in 1937. He has bachelor's and master's degrees from the Carnegie Institute of Technology and received the Ph.D. degree (number theory) from the University of Michigan in 1965. He taught at the Ohio State University and at DePauw University, from which he retired in 2004. He is the author of three books on mathematical oddities, The Trisectors, Mathematical Cranks, and Numerology, an elementary number theory text, and is the editor of two collections of mathematical pieces. He has edited the College Mathematics Journal, the Pi Mu Epsilon Journal, and two of the Mathematical Association of America's book series. He has served as the MAA's Pólya lecturer and has received its Distinguished Service Award. He is a member of the MAA, the American Mathematical Society, and the Society for Industrial and Applied Mathematics.
