1. The hardest part for me was remembering that associates aren't essentially identical in congruence classes the way they are in factoring. If we're dealing with the congruence class [ (7/9)x + 2 ], we can't multiply by 9 to clear the fractions or multiply by 9/7 to make it monic, since those would be different congruence classes.
2. I thought it was really cool how easily results from Z mod n translate to F[x] / (p(x)). Only one of the theorems (Corollary 5.5) had to make any changes, and they were very minor.
