WebAn ordered pair is a pair of objects in which the order of the objects is significant and is used to distinguish the pair. An example is the ordered pair (a,b) which is notably different than the pair (b,a) unless the values of each variable are equivalent. Coordinates on a graph are represented by an ordered pair, x and y. Web1.1Ordered pairs and Cartesian products • The elements of a set are not ordered. To describe functions and relations we will need the notion of an ordered pair, written as …
WebWith this definition an ordered pair is a set. Actually every object is a set in a mathematics which based on set theory. A × B is the Cartesian product of two sets. By definition it means that A × B := { ( a, b) ∣ a ∈ A and b ∈ B }. Using ordered pair definition you can write A × B into the form A × B = { { { a }, { a, b } } ∣ a ∈ A and b ∈ B }.

Ordered-Pairs After the concepts of set and membership, the next most important concept of set theory is the concept of ordered-pair. We have already dealt with the notion of unordered-pair, or doubleton. A doubleton is unordered insofar as the following is a theorem. can an american citizen hold dual citizenshipWebThe fact that the ordered pair (,) satisfies may be expressed with the shorthand notation () =. Another approach is taken by the von Neumann–Bernays–Gödel axioms (NBG); classes are the basic objects in this theory, and a set is then defined to be a class that is an element of some other class. fisher silk ponchoIf 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. Several set-theoretic definitions of the ordered pair are given below( see also ). … See more In mathematics, an ordered pair (a, b) is a pair of objects.
