In mathematics, an ordered pair (a, b) is a pair of objects. The order in which the objects appear in the pair is significant: the ordered pair (a, b) is different from the ordered pair (b, a) unless a = b. (In contrast, the unordered pair {a, b} equals the unordered pair {b, a}.)

The Axiom of Pairs basically says that if we have two sets, x and y, then we can form the new set { x. y }. You may be wondering why we don't start with singletons, but since { x, x } = { x }, the axiom also forms singletons at the same time.
