The set of integers (Z) is a … In mathematics, 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 … See more If A and B are sets and every element of A is also an element of B, then: A is a subset of B, denoted by $${\displaystyle A\subseteq B}$$, or equivalently, B is a superset of A, denoted by See more • A set A is a subset of B if and only if their intersection is equal to A. Formally: $${\displaystyle A\subseteq B{\text{ if and only if }}A\cap B=A.}$$ • A set A is a subset of B if and only if their union is equal to B.
