内容简介

A concise work on important topics in number theory, this classic text was devised by a prominent twentieth-century mathematician. Developed from a series of presentations to adult education courses, it explains the essentials of mathe-matics in a manner accessible to high school and college students as well as to other readers.
The mathematical work of author Abraham A. Fraenkel spans many decades and numerous areas. A well-known expert on combinatorial games, he also made advances in number theory, combinatorics, and computer science. In this text, he offers clear-cut explanations of natural numbers as cardinals, with discussions of positional notation and the ordering of numbers according to magnitude; natural numbers as ordinals, including Peano's axioms and the relation of ordinals to car-dinals;the theory of numbers, encompassing prime numbers and their distribu-tion, partitions of the circle, Fermat's simple and last theorems, perfect numbers,amicable numbers, and algebraic and ideal numbers; and rational numbers, with considerations of positive fractions, negative integers, and the field of rationals.
