Interesting concept

An interesting concept I found in Chapter 6 are compound claims. A compound claim is a claim that contains one or more claims, but seen as only one claim. A word such as "or" is used to connect two or claims together to form one compound claim. Here is an example:

Either Mary will win the class election or Michael will win

In this example, there are obviously two different claims but seen only just one claim. Either mary or michael is going to win the election, but not both.

1.) Mary will win the class presidential election
2.) Michael will win the class presidential election.

Another important concept in Ch. 6 is the contradictory of a claim. Basically, the contradictory of a claim is the opposite of a compound claim. It's also known as the negation of a claim. It's used to make a compound claim false. Assume that the compound claim is "michael is a genius" and the contradictory of that claim would be "Michael is not a genius".
