So I’ve already painstakingly articulated A LOT about conditional statements, which we went over in class today. So instead of outlining my notes again, I thought I’d focus on one thing I was confused about in class that I want to make sure I get right: The difference between being an element and being a subset. The example that confused me a little was:

*S ⊆ ℤ (where S is a variable set)*

The truth set would have to be comprised of sets itself, NOT just integers. An integer is an **element** of the set that is a subset of all integers. The proper way to explain the truth set for this open sentence would be {all sets of integers}, NOT {all integers}. Integers are elements, sets of integers are a subset to all integers.

Make sense? Think so.
