## About

### Overview

Abstract Algebra: An Introduction is set apart by its thematic development and organization. The chapters are organized around two themes: arithmetic and congruence. Each theme is developed first for the integers, then for polynomials, and finally for rings and groups. This enables students to see where many abstract concepts come from, why they are important, and how they relate to one another. New to this edition is a "groups first" option that enables those who prefer to cover groups before rings to do so easily.

### Features and Benefits

• The text may be used for either courses that cover rings before groups (as in earlier editions) OR courses that cover groups before rings.
• The flexible design of this text makes it suitable for courses of various lengths and different levels of mathematical sophistication.
• The chapters are organized around two themes, arithmetic and congruence, that are developed first for the integers and then for rings, polynomials, and groups.
• The emphasis throughout is on clarity of exposition.
