Unary Operation

A unary operation is a mathematical operation that takes only one input and produces a corresponding output. It is an operation performed on a single operand.

Sense 1: Arithmetic

In arithmetic, a unary operation is typically denoted by a symbol placed before or after a number to perform specific mathematical transformations.

Example sentence: The unary operation of negation, denoted by the minus sign (−), changes the sign of a number. For example, the unary operation of −5 results in -(-5) which equals 5.

Sense 2: Computer Science

In computer science, a unary operation refers to an operation that operates on only one input value. It is commonly used in programming languages to manipulate the value of a single operand.

Example sentence: The unary increment operator (++), when applied to a variable, increases its value by one. For example, var x = 5; x++; will assign the value 6 to the variable x.

Sense 3: Set Theory

In set theory, a unary operation is a function that takes a single set as an input and produces another set as the output. It performs a transformation based on the given set.

Example sentence: The unary operation of complement, denoted by A', returns the set that contains all the elements not present in set A. For example, if set A is {1, 2, 3}, then the complement of A is {4, 5, 6}.
