Term: Unary

Description:

In mathematics, the term "unary" refers to an operation or a function that involves only one element, operand, or variable.

In computer programming, "unary" commonly relates to an operator or a function that operates on a single operand or argument.

Additionally, "unary" can also refer to a numbering system with the base of one, as opposed to the usual decimal system.

Examples:

1. As a mathematical operator:

The unary minus operator (-) inverts the sign of a number. For example, in the expression -5, the minus is a unary operator.

2. In computer programming:

In some languages, the increment operator (++), which increases the value of a variable by one, is a unary operator. For instance, in the expression x++, the plus plus is a unary operator.
