Reciprocal
The term "reciprocal" refers to a mutual relationship where two parties provide each other with similar benefits or actions. In mathematics, it specifically describes the relationship between a number and its multiplicative inverse. For example, the reciprocal of 2 is 1/2, as multiplying them together equals 1.
In everyday life, reciprocal relationships can be seen in friendships, where support and kindness are exchanged. For instance, if one friend helps another move, the other might later assist with a different task. This mutual exchange fosters trust and strengthens connections between individuals.
