Sec. 7, 10.4, Due March 16, 2012

As we've already covered this in class there weren't as many potentially confusing thing.  The proof that the power set of A and 2^A are numerically equivalent still doesn't quite make sense though.  That and the proof showing that a bijection doesn't exist between the set A and it's power set.  If we're still on this section it would be helpful to see these again.
