Pinter's book does what very few mathematics books do. It perfectly balances rigour and intuition. His style is so compelling that parts of the book pull you in like reading a novel. I mainly used it as a supplemental text in my first few abstract algebra courses. However, I credit a large part of my love of the subject to finding Prof. Pinter's book at the right time.

Is it perfect? Not quite. He puts some material in the exercises that probably deserved to be treated in the main part of the text. However, it is unlikely that you will be using this book as your only reference, so I don't feel this is much of a flaw.

Bottom line. For not much more than \$10, this belongs in the library of everyone who has any interest in mathematics.

that certainly does seem well written, at least from what little i can see on amazon. i wish i had known about this book when teaching undergrad courses on proof and intro to algebra.

Great book. I think a (HS) student with a deep interest in mathematics would enjoy his informal, yet rigorous exposition to the material. If one already knows proofs, a more advanced book would probably be more appropriate.

I agree with the other reviews. This is a lovely little book, rigorous but extremely well motivated. The main text carries you efficiently from first principles through Galois theory without too many detours. The exercises develop many interesting side topics and examples, with the more difficult material carefully broken down into step by step exercises. I wish I had known about this book when I was first learning algebra. Considering its low price, pretty much everyone should own this book.

Pinter's text served as my gateway back into rigorous mathematics! It is well-written and organized. There are a plethora of perfecty chosen problems at the end of each chapter. I highly recommend this text to anyone. In fact, I will be suggesting this text to one of my brighter students for summer reading. (The student will be a senior in high school next year.)
