(definition)
Definition: (1) Of a boolean, 0 if 1, or 1 if 0. See not. (2) Of a set A, a set having all the members which are in the universe, but not in A.
See also difference, union, intersection.
Note: The complement can be seen as the difference of a set and the universe, or the universal set. That is, A' = U - A. If the universe is {1, 2, 3, 4}, then the complement of {1, 2} is {3, 4}, and the complement of {3} is {1, 2, 4}.
