"Why Is Abstract Algebra Useful? " essay on the author`s website shows students the importance of studying abstract algebra and its applicability to everyday life. This motivational essay can be incorporated into a lesson on the first day of class, or can serve as a motivational tool further along in the course. Coverage of proof writing is provided on the instructor`s website in the updated essay "Advice for students learning proofs." This essay provides basic guidance for students encountering proof writing for the first time or needing to freshen their skills. This text focuses on abstract algebra as a contemporary subject, with concepts and methodologies currently being used by computer scientists, physics, and chemists. Extensive coverage of groups, rings, and fields, plus a variety of non-traditional special topics. A good mixture of now more that 1750 computational and theoretical exercises appearing in each chapter and in Supplementary Exercise sets that synthesize concepts from multiple chapters. Emphasis on computation and proof writing, with an abundance of exercises to help students develop both skills.
