Can someone please help me with this I am not getting the same answers as the examples in the book.
U={1,2,3,4,5,6,7,8}
A={1,2,3,4,7,8}
B={1,2,4,5}
Determine (A'UB')n(AUB)'

college Mathematics 
Reiny
A' = {5,6)
B' = {3,6,7,8}
(A'UB') = {3,5,6,7,8}
(AUB)' = {6}
I don't understand the operator n
is it supposed to stand for "intersection" ?
if so, then
(A'UB') ∩ (AUB)' = {6}
if not, let me know what the n stands for
