If A = {X element of N such that X<7} and B={X element of Z such that the absolute value oof X-5 is less than 3, and C=2,3} find (A symmetric difference B) \ C
If A = {X element of N such that X<7} and B={X element of Z such that the absolute value oof X-5 is less than 3}, and C={2,3} find (A symmetric difference B) \ C
they are asking for the set $\displaystyle [(A - B) \cup (B - A)] - C$ or equivalently, $\displaystyle [(A \cup B) - (A \cap B)] - C$
