A Guide to Elementary Number Theory is a 140-page exposition of 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, some of which approach 500 pages in length. It will be especially useful to graduate student preparing for the qualifying exams. Underwood Dudley 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 all published by the Mathematical Association of America. He has also served as editor of the College Mathematics Journal, the Pi Mu Epsilon Journal, and two of the Mathematical Association of America's book series. 410 0$aDolciani mathematical expositions ;$vno. 41. 410 0$aMAA guides ;$vno. 5. 606 $aNumber theory 615 0$aNumber theory. 676 $a512.7/2 686 $aSK 180$2rvk 700 $aDudley$b Underwood$01190545 712 02$aMathematical Association of America, 801 0$bUkCbUP 801 1$bUkCbUP 906 $aBOOK 912 $a9910809577103321 996 $aA guide to elementary number theory$94117935 997 $aUNINA
