Section 6.1 (part2) and section 6.2 (part 1). Due Tuesday, February 21

The reading for today was the rest of section 6.1: Ideals and Congruence, and then the first half of section 6.2: Quotient Rings and Homomorphisms.

The most difficult concept for me was the idea of "cosets."

I am wondering how general these ideas can possibly get. It seems that each section just generalizes further than the last, making it more "abstract." I guess that is the point. I believe that we are near the end though. The next chapter is about groups, but I am sure we will be using some of the ideas from the first six chapters.
