To say that a set A is tidy means that, for every x, if x is an element of A, then x is a subset of A. Also recall that, for any set X, we have defined the successor of X, S ( X ), to be the set X ∪ { X }.

- Suppose that U and V are both tidy. Prove that U ∩ V is tidy.
- Suppose that X is tidy. Prove that S ( X ) is tidy.
