Set Difference A - B, the set containing those elements that are in A but not in B Set Symmetric Difference A ⊕ B: the set of elements that are a member of exactly one of A and B, but not both. An alternative definition of the symmetric difference operation is: A ⊕ B = ( A - B ) ∪ ( B - A ) Set Complement the set of all elements in U that are not elements of A. An alternative definition of A is U - A. Set Intersection A ∩ B: the resulting set that contains...
