inverses
Reciprocals in math
Inverses are things that reverse or undo each other.
In mathematics, additive inverses sum to zero (5 and -5), while multiplicative inverses multiply to one (2 and ½).
More broadly, inverses are mirror-image counterparts: Their personalities were inverses—she was cautious where he was reckless.
The singular inverse typically functions as a noun or adjective: the inverse relationship between supply and price.
