Undergraduate Algebra

This textbook offers an innovative approach to abstract algebra, based  on a unified treatment of similar concepts across different algebraic  structures. This makes it possible to express the main ideas of algebra more clearly and to avoid unnecessary repetition.The book consists of two parts:áThe Language of AlgebraáandáAlgebra in Action.áThe unified approach to different algebraic structures is a primary feature of the first part, which discusses the basic notions of algebra at an elementary level. The second part is mathematically more complex, covering topics such as the Sylow theorems, modules over  principal ideal domains, and Galois theory.Intended for an undergraduate course or for self-study, the book is written in a readable, conversational style, is rich in examples, and contains over  700 carefully selected exercises.
