relative complement

Noun

 * 1)  The set containing exactly those elements belonging to B but not to A.

Usage notes

 * In mathematical expressions, the relative complement of A in B is denoted B ∖ A according to the ISO 31-11 standard (sometimes written B &minus; A, but this notation is ambiguous, as in some contexts it can be interpreted as the set of all b &minus; a, where b is taken from B and a from A).
