This is a textbook for a first-semester abstract algebra course. Our focus in this book is the study of algebraic structures called 'groups.' We will explore rigorous mathematical notions of similarity and difference by introducing the concept of isomorphism, and readers will gain exposure to mathematical proofs and see plenty of specific examples demonstrating more general ideas.
