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)'

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
