👉 In mathematics, a relationally defined set is a collection of sets that are related in some way. This means that each element from one set can be related to an element from another set through a unique relationship or function. For example, if we have two sets A and B, then the relation "A is related to B" defines a subset of the Cartesian product (set of all ordered pairs) between A and B. For example: 1. A = {apple, orange} 2.
