This edition has been revised and expanded, particularly the material on rings and fields, to provide a comprehensive first course in abstract algebra. The text is written for the student encountering this subject for the first time - the treatment is clear and patient, but also provides enough depth to demonstrate the insights that abstract algebra offers. The book includes many worked examples and each chapter contains a set of graded exercises, with partial solutions.

The first and second editions of this successful textbook have been highly praised for their lucid and detailed coverage of abstract algebra. In this third edition, the author has carefully revised and extended his treatment, particularly the material on rings and fields, to provide an even more satisfying first course in abstract algebra.
