Section 2.3

Difficult: I understood all the proofs in this section, but I am having a hard time applying them to examples and seeing how they will come in useful. For example, I understand how the proof of Corollary 2.9 works, but I wish there was an example in the book that would tell me how to use it.

Reflective: I think it's so interesting that the prime numbers create a special case and have special properties. Also, the fact that a and n being relatively prime makes a difference is also really cool. I've never known that prime numbers have so many special properties, and I am excited to learn more about them.
