Superset vs. Subset — What's the Difference?

(set theory) (symbol: ⊇) With respect to another set, a set such that each of the elements of the other set is also an element of the set.

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). A is a subset of B may also be expressed as B includes (or contains) A or A is included (or contained) in B. The subset relation defines a partial order on sets.
