With MEMBERSHIP, you must say an element of the set A

with SUBSETS, you must decide if the set A is a subset of B

with UNION you have to enter an element of A U B

with INTERSECTION you have to enter an element of A ∩ B

with DIFFERENCE you have to enter an element of A - B

with CARDINALITY you must know the cardinality of a set

with CARTESIAN PRODUCT you have to complete a pair (a, b) of the cartesian product of two sets

The application guide you throughout the different problems.
