Sections 4.3-4.4 Due May 14

1. It will be hard to get to this new way of thinking about roots. Like when it says that a root is an induced function from R to R that maps a to O. Also I didn't understand what corollary 4.19 on the bottom of page 4.4 was saying.
2. The definition of primality or irreducibility was just like with normal integers. As was the unique factorization. The proofs were similar too. I think that this section seemed pretty straight forward and similar to what we've already done.
