2.1-2.4, due on January 9

1. The most difficult part of this reading was the last part of the section on implications. Some of the alternate wordings seemed a little bit confusing. Like if P implies Q, you can say "If P, then Q," but you can also say, "P only if Q." At first I struggled with how that is different from, "P if and only if." The more I thought about it, the more I understood it, but I think it could trip me up on a test if I wasn't careful. Maybe I shouldn't give you any ideas!

2. I've never used the term "disjunction" for the OR statement before. It doesn't really seem to describe what it does. Disjunction is like separating two things, but OR-ing two things is like taking both of them and mixing them up together.
