Unary operation
From Wikipedia, the free encyclopedia.

In mathematics, a unary operation is an operation with only one operand. For instance, logical negation is a unary operation on truth values and squaring is a unary operation on the real numbers. A unary operation on the set S is nothing but a function S → S.
