Are there more books like "Abel's Theorem in Problems and Solutions"? The book "Abel's Theorem in Problems and Solutions" saved me in Algebra. I have over 5 books in Algebra, but Abel shines in its student-friendliness. It is easy to approach, full of exercises, solutions and relevant theories. Please, do not understand me wrong. I am an undergraduate at Mathematics, and I enjoy formal style like in Bourbakis. I just love self-contained books like the Abel, because I have to self-study a lot. Are there more books like the Abel?
