WebOct 7, 2016 · The textbook definition is simple – If the order matters, we are talking about ordered pairs, if order does not matter we are referring to unordered pairs. But this idea probably needs more elaborating than just the definition. Let us do this with an example – In how many ways can two natural numbers add up to 15?
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. Then the characteristic (or defining) property of the ordered pair is: The See more If one agrees that set theory is an appealing foundation of mathematics, then all mathematical objects must be defined as sets of some sort. Hence if the ordered pair is not taken as primitive, it must be defined as a set.
