Abstract Algebra A Proof-Based Approach with Complete Solutions

By Mir Hossain

Abstract Algebra can feel intimidating-until you see the patterns clearly and practice the proofs step by step.
This book is a student-friendly, proof-focused guide designed to help you understand the core structures of algebra and confidently solve problems the way instructors grade them.

Inside, you'll build mastery through clear explanations, worked examples, and fully written solutions that model the logic and structure of strong mathematical writing.

What you'll learn (with complete solutions)

Groups, subgroups, cyclic groups, permutations, and group actions

Homomorphisms, kernels, images, isomorphism theorems, and quotient groups

Rings, ideals, ring homomorphisms, and quotient rings

Integral domains, fields, polynomial rings, and factorization

Modular arithmetic, congruences, and applications to number theory

Proof techniques used in abstract algebra: induction, contradiction, contrapositive, and construction proofs

Why this book works

Proof-based approach: every major idea comes with a proof blueprint you can reuse

Complete solutions: no skipped steps-solutions are written in a way you can learn from

Practice-first design: definitions → examples → exercises → solutions (ideal for self-study)

Exam-ready coverage: matches the standard undergraduate abstract algebra sequence

Whether you're taking your first course in abstract algebra or reviewing for an exam, this book helps you move from "I recognize the topic" to "I can prove it and solve it."
