Will enrich library collections serving curricula with theory of numbers courses —Choice

If you are fascinated by numbers you will thoroughly enjoy this book—The Mathematics Teacher

A collection of the interesting properties of various integers, touching frequently on contemporary research, and generally lacking proofs for the results stated. Most of the material presented belongs to elementary mathematics in the sense that no deep or profound mathematical background is required. Much of the material is drawn from the theory of numbers.—Annotation c. Book News, Inc., Portland, OR (booknews.com)

What a perfect title! All mathematicians, independent of their specialty or level of expertise, are to some extent followers of the philosophy of Leopold Kronecker. As you may recall, he authored the famous phrase: "God made the integers; all else is the work of man." Hooked a bit more than most, the author presents his extensive collection of interesting facts about the positive integers...A joy to read and ponder, this book is a welcome addition to the body of mathematical literature. It belongs in every mathematical library. —Charles Ashbacher, Journal of Recreational Math

This charming book contains a great number of interesting stories and theorems (mostly of the number theoretical character) which are connected with more than 250 natural numbers. Many references. The goal of this really nice book is to show the beauty of many parts of mathematics. Some results presented here will be surprising even for experts. Warmly recommended to specialists as well as to amateurs. —EMS Newsletter
