www.math.fsu.eduThe intersection of two sets denotes the elements that the sets have in common, or the "overlap" of the two sets. S ∩ T = {x|x∈ S and x∈ T}. The union of two sets merges the two sets into one "larger" set. S ∪ T = {x|x ∈ S or x ∈ T}. The complement of a set consists of all elements in the universal set that are not in the given set.

math.mit.eduAxiom 1b. Consider two sets A and B. Then A = B if and only if x ∈ A ⇔ x ∈ B. A.3. Operations on sets. Given two sets U, V , a natural thing to do is to join the elements of U and V into a single set: Definition 1 (Union of two sets). Let U, V be sets. The union of U and V , U ∪V , is the set whose elements x are characterized by
