A Guide To Elementary Number Theory (Dolciani Mathematical Expositions)
Anyone who wishes to learn what elementary number theory is about and some of its important, yet open, questions will not find a better resource.The author provides the basic pertinent definitions and theorems in elementary number theory, ranging from greatest common divisors to quadratic recipocity to Waring's problems. A valuable resource for any student especially graduate students preparing for qualifying exams. --J. T. Zerger, Choice MagazineThis is one of the books in the MAA Guides series, others includeA Guide to Complex Variables, Real Variables, and Topology, etc. Since this is a small book, the book review must be short. What we would like to say is that this is a very nice book for anyone interested in number theory. However, if you want to know more about number theory you can read this book first, make yourself familiar with the basic concepts and ideas of number theory, then read Baker's introductory book or Hardy's comprehensive book. --Song Yan, Sigact News
