In mathematics, a set A is a subset of a set B if all elements of A are also elements of B; B is then a superset of A. It is possible for A and B to be equal; if they are unequal, then A is a proper subset of B. The relationship of one set being a subset of another is called inclusion (or sometimes containment ).

Jun 19, 2024 · A subset is a set whose elements are all members of another set. In other words, a subset is a part of a given set. If A and B are two sets, we say A is a subset of B if every element of A is also an element of B.
Set A A is a subset of set B B if every member of set A A is also a member of set B B. Symbolically, this relationship is written as A ⊆ B A ⊆ B . Sets can be related to each other in several different ways: they may not share any members in common, they may share some members in common, or they may share all members in common.
