In the union of set A with set B, S = A [union] B, the total membership of the new set S is the same as would be arrived at by the algebraic addition S = A + B but only when sets A and B are disjoint or mutually exclusive.
By the operations of intersection and intersection-complementation (negation), one can construct mutually exclusive sub-sets out of overlapping sets and algebraic addition can be applied to the sub-sets' membership when their contents are joined by union.
