The set theory clearly explains what an intersect does. In mathematics, the intersection of A and B (A ∩ B) is the set that contains all elements of A that also belong to B. WebIn set theory, the union (denoted by ∪) of a collection of sets is the set of all elements in the collection. It is one of the fundamental operations through which sets can be combined and related to each other. A nullary union refers to a union of zero sets and it is by definition equal to the empty set..
