Just from the reading, understanding relations was very difficult. Even though I've read some other things too, relations don't exactly make sense. The relation should contain ordered pairs for the examples we're talking about, but it seems to me that normal relations would be after the order of y=3x or some other equation. Yet the relation seems to be definied much more loosely than that. We're given random sets of ordered pairs between two matrices but to me there doesn't really seem to be a pattern in the relation. Also the general lack of examples in this section of the book is kind of disappointing.
Although I'm not sure how they're used yet, I think properties of relations are kind of fun. It's a little bit more finite than a lot of the things we've talked about up til now. The relation either contains these sets of ordered pairs or it doesn't so it's easy to see what properties the sets have.
