In mathematics, especially in set theory, a set *A* is a **subset** of a set *B*, or equivalently *B* is a **superset** of *A*, if *A* is "contained" inside *B*, that is, all elements of *A* are also elements of *B*. *A* and *B* may coincide. The relationship of one set being a subset of another is called **inclusion** or sometimes **containment**.
