Sections 2.4 through 2.4.1, due on September 6

I found the most difficult part of the material to be to get all of the definitions matched up with what I all ready know. For example, I have never heard of a "Residue Class", I have always just called them equivalence classes. Getting all of the terminology straight was the most difficult.

I like how they took the general ideas from concepts such as modulo, and built them out of things which we have all ready covered such as the division algorithm.
