A Friendly Introduction to Abstract Algebra offers a new approach to laying a foundation for abstract mathematics. Prior experience with proofs is not assumed, and the book takes time to build proof-writing skills in ways that will serve students through a lifetime of learning and creating mathemati

Taking a slightly different approach from similar texts, Introduction to Abstract Algebra presents abstract algebra as the main tool underlying discrete mathematics and the digital world. It helps students fully understand groups, rings, semigroups, and monoids by rigorously building concepts from f
The emphasis in this book is on examples and exercises, and they provide much of the motivation for the material. The author have also tried to provide some historical comment and to examine the connections between modern algebra and other fields. (These comments and connections often appear in the
