this was the book that I used for a course in graduate school the name basic algebra kind of implies that it's a book that will teach you to factor or solve quadratic equations or something of that nature but it's actually an abstract algebra book and it's kind of a fun book because at least two people have seen this book and they've said basic alg...

Questions & Answers

Q: What is the main misconception about the book "Basic Algebra"?

The main misconception about the book is that it teaches basic algebra, such as solving equations, when it is actually a graduate-level abstract algebra book.

Q: Why didn't the presenter use the book extensively for their course?

The presenter had already taken two other courses on abstract algebra before taking the course that required the book, so they had already gained a lot of experience in the subject.

Q: What does the presenter emphasize about being good at mathematics?

The presenter emphasizes that being good at mathematics is often a result of practice, hours of effort, and gaining experience rather than inherent brilliance or intelligence.

Q: What are some of the topics covered in the book "Basic Algebra"?

The book covers topics such as group theory, linear transformations, commutative rings, fields, and modules over non-commutative rings.
