In mathematics, the additive inverse, or opposite, of a number n is the number that, when added to n, yields zero. The additive inverse of F is denoted ?F.
The additive inverse of a number is the number that will add to it to make zero. For example, the additive inverse of 7 is -7 because: 7 + (-7) = 0 Basically, it's the number with the opposite sign. Incidentally, zero is the only number that is its own additive inverse. -2 and 2 -81 and 81 15 and -15 -3.5 and 3.5 0 and 0
It's the opposite of a number.
