In mathematics, the intersection (denoted as ) of two sets A and B is the set that contains all elements of A that also belong to B (or equivalently, all elements of B that also belong to A), but no other elements.A set is a collection of distinct objects, considered as an object in its own right. Sets are one of the most fundamental concepts in mathematics.
