Ordered pair in set theory
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}.) Ordered pairs are also called 2-tuples, or … See more Let $${\displaystyle (a_{1},b_{1})}$$ and $${\displaystyle (a_{2},b_{2})}$$ be ordered pairs.
