I am new to studying abstract algebra (and math in general). I've been reading Gilligan and Pinter's books. I am trying to improve my understanding by doing exercises. However none of the books I am reading seem to come with exercise solutions.
Is there an abstract algebra book with lots of exercise with solutions?
I am confused as to why none of the math books come with complete exercise solutions. How do people verify that their answers are right.
A simple search on Google shows the following:
