reciprocals
Numbers multiplying to one
Reciprocals are things that correspond to each other in a mutual or inverse relationship.
In mathematics, a reciprocal is a number that when multiplied by another yields one—the reciprocal of 4 is 1/4.
More broadly, reciprocal arrangements involve mutual exchange: reciprocal trade agreements, reciprocal obligations between allies.
The adjective reciprocal describes anything given or felt in return.
