From rings to modules to groups to fields， this undergraduate introduction to abstract algebra follows an unconventional path。 The text emphasizes a modern perspective on the subject， with gentle mentions of the unifying categorical principles underlying the various constructions and the role of universal properties。 A key feature is the treatment of modules， including a proof of the classification theorem for finitely generated modules over Euclidean domains。 Noetherian modules and some of the language of exact complexes are introduced。 In addition， standard topics - such as the Chinese Remainder Theorem， the Gauss Lemma， the Sylow Theorems， simplicity of alternating groups， standard results on field extensions， and the Fundamental Theorem of Galois Theory - are all treated in detail。 Students will appreciate the text's conversational style， 400+ exercises， an appendix with complete solutions to around 150 of the main text problems， and an appendix with general background on basic logic and na�ve set theory。
