5.2-5.3, due September 29

What was the most difficult part of the material for you?
I had a hard time grasping the technical explanation of proof by contradiction. When I read about how to do it in my own proofs, I went back and read the explanation again and it made more sense.

What was the most interesting part of the material for you?
I think it's fun to prove things by contradiction. It's an interesting strategy to have the negation of a statement imply a contradiction. The trick is to figure out what the contradiction is.
