Sections 5.1-5.3 Due May 14

1.  The extensions didn't make any sense. Especially after they replaced x^2 with x+1. The whole extension field idea was confusing.
2. Everything else seemed exactly like normal equivalence classes. The proofs were the same. The multiplication and addition tables worked the same. I think the idea of equivalence classes with something like polynomials is a little bit silly though. It seemed like it was just taking a simple enough idea and making it as complicated as possible by applying it to polynomials rather than just integers. However I would be interested to here how something like this would be useful.
