## A Pathway Into Number TheoryNumber theory is concerned with the properties of the natural numbers: 1,2,3,.... During the seventeenth and eighteenth centuries, number theory became established through the work of Fermat, Euler and Gauss. With the hand calculators and computers of today, the results of extensive numerical work are instantly available and mathematicians may traverse the road leading to their discoveries with comparative ease. Now in its second edition, this book consists of a sequence of exercises that will lead readers from quite simple number work to the point where they can prove algebraically the classical results of elementary number theory for themselves. A modern high school course in mathematics is sufficient background for the whole book which, as a whole, is designed to be used as an undergraduate course in number theory to be pursued by independent study without supporting lectures. |

With problems ordered in a discovery fashion and historical background behind each topic, this book presents a great way to teach number theory. The book contains a fair amount of interesting questions as well; however, it lacks a big and necessary portion of a math textbook: the information and worked examples. Truly a "pathway" into number theory, it would work well as a study guide and exercise book, but not a textbook.
