2.2, due on January 12

1. (Difficult) "What was the most difficult part of the material for you?"
The most difficult part of the material for me was how in the previous section we had been dealing with mods and now we are dealing with Z and my mind gets confused on transferring what I had learned about mods over to calling it all Z's. I mean, I think all the Z stuff is like using the idea of a mod or a change of base, but I'm still confused when approaching problems like the ones on the homework.

2. (Reflective) Write something reflective about the reading. This could be the answer to the question "What was the most interesting part of the material?" or "How does this material connect to something else you have learned in mathematics?" or "How is this material useful/relevant to your intellectual or career interests?" or something else.
The most interesting part of the material was Theorem 2.7 where there were like 10 properties that hold true for classes in Zn. I think that is fascinating how there are all these properties - very cool. Also, the proofs for them seem simple enough that it is interesting to see how they all simply work.
