5.3, due on February 13

Difficult: This section was very abstract. (kinda like the title of the course suggests it will be...funny.) Theorem 5.11 I don't entirely understand. Why is it important? And the proof doesn't make sense yet.

Reflective: Theorem 5.10 makes sense because it is analogous to the integers mod a prime. But 2 of the 3 proofs I don't really follow. Are groups more complicatied or less complicated than rings?
