👉 In mathematics, a superset is a set that contains all of its members. In other words, if A is a superset of B, then for every element x in A, there exists an element y in B such that x is not equal to y. For example, the set {1, 2, 3} is a superset of the set {4, 5, 6}, because any member of {1, 2, 3} can be replaced
