Ebook: A Book of Abstract Algebra

Pinter writes a book the rest of us non-mathematical geniuses can understand. The book aims for the average higher level math student in group and field theory. I used it to supplement a college course in this area returning after 25 years out of college. The book is broken into nice, short chapters that progress well. A little light on isometries in R2 and a supplement with answers would be nice.

The earlier editions are just as valid and much cheaper. This stuff hasn't changed much in a century or two.
