Opposite number

In mathematics, opposite number or additive inverse of any number is a number n which, if added to n, results in 0 (the identity element of addition). The opposite number for n is written as −n.^[1]^[2]^[3] For example, −7 is the opposite number of 7, because $-\!7+7=0$ .

For positive numbers, the opposite number is simply the negative version of the number. For negative numbers, the opposite number is the positive version of the number.
