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 an unary operation on A.
Common notations are prefix notation (e.g. +, −, not), postfix notation (e.g. factorial: n!), functional notation (e.g. sin x or sin (x)), and superscripts (e.g. transpose AT). Other notation exists as well, for example in the case of the square root a horizontal bar over the argument extending the square root sign can indicate the extent of the argument.

Famous quotes containing the word operation:
“Waiting for the race to become official, he began to feel as if he had as much effect on the final outcome of the operation as a single piece of a jumbo jigsaw puzzle has to its predetermined final design. Only the addition of the missing fragments of the puzzle would reveal if the picture was as he guessed it would be.”
—Stanley Kubrick (b. 1928)
