This book is a concise and carefully written introduction to topics in <br />
commutative algebra, with an emphasis on worked examples and applications. The <br />
elegant algebraic theory is combined with applications to number theory, <br />
problems in classical Greek geometry, and the theory of finite fields, which has <br />
important uses in other branches of science. Topics covered include an <br />
introduction to rings and Euclidean rings, UFDs and PIDs, factorization of <br />
polynomials, fields and field extensions, and algebraic numbers. This book could <br />
form a springboard to further study of abstract algebra, but is also eminently <br />
suitable as the course text for an entire undergraduate course. <br />
