Throughout the book a historical perspective has been adopted and emphasis is given to some of the subject's applied aspects; in particular the field of cryptography is highlighted. At the heart of the book are the major number theoretic accomplishments of Euclid, Fermat, Gauss, Legendre, and Euler, and to fully illustrate the properties of numbers and concepts developed in the text, a wealth of exercises have been included. It is assumed that the reader will have 'pencil in hand' and ready access to a calculator or computer. For students new to number theory, whatever their background, this is a stimulating and entertaining introduction to the subject.Number theoryNumber theory.512/.72Tattersall James J(James Joseph),1941-62406UkCbUPUkCbUPBOOK9910450101703321Elementary number theory in nine chapters374646UNINA01118nam a22002531i 450099100297203970753620040502170332.0040624s1985 it a||||||||||||||||ita b13005418-39ule_instARCHE-096309ExLDip.to Beni CulturaliitaA.t.i.
