Section 20 due October 22

1. I can understand it... but I'm just trying to figure out how it's going to relate to proof techniques. This is probably the intro chapter and then we'll start applying it in the next section? That's my guess. Also, I'm not totally solid on how to tell what is in the set R. Like, sometimes it's just arbitrarily given and sometimes it's by some rule? I guess it's just a set.

2. This class is great. I feel like I'm learning everything that's under the hood of regular mathematics. For example, this section was on relations and then proceeded to tell me that ours standard operators +, <, >, etc. are all just common relations. That's so cool. I'm not sure which came first, the relations or the operators, but it's cool to see them in a new light like that.
