WTF does this mean?
Don't tell me the answer since it is my homework, but wth is a U or (up-side-down) U with an exponent?
I'm given Sets A (sub 1 through 4) so I assume the i=1 means set A(sub 1). ok, but then the U (meaning union i suppose cause it's a set problem) with the exponent 4? does that mean take all the elements of the set and quad them???
