Difficult: Section 3.5 was the more difficult section of the two for me. It was hard for me to understand exactly what was going on with having the result coming first. It seemed like the book was trying to make it be different, but in a way it seems that for most proofs you start with the end result and then go about trying to work your way to prove that result. So I didn't really understand what they meant by that.
Reflective: I like the section about proof by cases and subcases found in 3.4. What I like about this is the idea of breaking things down into smaller pieces. This reminds me of art paintings that are composed of just a bunch of dots. Where when you look up close, all you see are all the different colors of dots, but then when you step back you begin to see the whole picture. This seems to be the same way of these types of proofs where there are a bunch of little pieces, or dots, that come together to form the whole picture.
