Unary operation

In mathematics, a unary operation is an operation with only one operand, i.e. a single input. Specifically, it is a function where A is a set. In this case f is called a unary operation on A. Common notations are prefix notation, postfix notation, functional notation, and superscripts. Other notations exist as well. For example, in the case of the square root, a horizontal bar extending the square root sign over the argument can indicate the extent of the argument.
