Opposite

An opposite is the number the same distance from zero on the other side of the number line. The opposite of 3/4 is −3/4, and the opposite of −5 is 5.

A number and its opposite add to zero, so the pair is also called additive inverses. The opposite is not the same as the absolute value: the absolute value is the distance from zero and is always positive, while the opposite flips the sign.
