Question

what is subsets in maths ???​

Answer 1

A set A is a subset of another set B if all elements of the set A are elements of the set B. In other words, the set A is contained inside the set B. The subset relationship is denoted as A⊂B.

Answer 2

A set A is a superset of another set B if all elements of the set B are elements of the set A. The superset relationship is denoted as A⊃B. For example, if A is the set {♢,♡,♣,♠} and B is the set {♢,♣,♠}, then A⊃B but B⊅A.
