In particular, it adequately expresses 'order', in that is false unless . There are other definitions, of similar or lesser complexity, that are equally adequate: Ordered pairs are also called 2-tuples, 2-dimensional vectors, or sequences of length 2. The entries of an ordered pair can be other ordered pairs, enabling the recursive definition of ordered n-tuples (ordered lists of n objects). For example, the ordered triple (a,b,c) can be defined as (a, (b,c)), i.e., as one pair nested in another. Illustrated definition of Ordered Pair: Two numbers written in a certain order. Usually written in parentheses like this: (12,5) Which Ordered pairs of scalars are sometimes called 2-dimensional vectors. (Technically, this is an abuse of notation since an ordered pair need not be an element of a vector space.) The entries of an ordered pair can be other ordered pairs, enabling the recursive definition of ordered n-tuples (ordered lists of n objects).

36), though there exist several other definitions. Ordered pairs are also called 2-tuples, 2-dimensional vectors, or sequences of length 2. The entries of an ordered pair can be other ordered pairs, enabling the recursive definition of ordered n-tuples (ordered lists of n objects). For example, the ordered triple (a,b,c) can be defined as (a, (b,c)), i.e., as one pair nested in another. An 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.

(The notation (a, b) is also used to denote an open interval on the real number line; context should make it clear which meaning is meant. 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.

Booleans such as Peirce and Schroder, and set theorists who followed Kuratowski, differed on this point only in their respective notions of ordered pair and class. They were agreed that rela-tions were 'classes' of 'ordered pairs.' Possibly Russell clung to an inten- The cartesian product of two sets needs to brought across from naive set theory into ZF set theory. The Kuratowski construction allows this to be done withou Kuratowski's definition. In 1921 Kazimierz Kuratowski offered the now-accepted definitioncf introduction to Wiener's paper in van Heijenoort 1967:224. van Heijenoort observes that the resulting set that represents the ordered pair "has a type higher by 2 than the elements (when they are of the same type)"; he offers references that show how, under certain circumstances, the type can be 2011-05-17 2009-08-03 Wikipedia, Ordered pair - Kuratowski definition; Last revised on May 8, 2017 at 16:06:34.

Angry bee 06:01, 7 February 2011 (UTC) Forget not being chornolgoglogyical, it's really hard to read. Kazimierz Kuratowski's father, Marek Kuratowski was a leading lawyer in Warsaw. His work in set theory considered a function as a set of ordered pairs and this made the function notion as proposed by Frege, Charles Peirce and Schröder redundant.

Ordered pairs are also called 2-tuples, 2-dimensional vectors, or sequences of length 2. The entries of an ordered pair can be other ordered pairs, enabling the recursive definition of ordered n-tuples (ordered lists of n objects). For example, the ordered triple (a,b,c) can be defined as (a, (b,c)), i.e., as one pair nested in another. You seem to be asking "what is the definition of 'ordered pair'".

one can prove (from Zermelo's axioms) that. Then we can define the Cartesian product of A and B:.

We would therefore add to the STLC $\zeta$ and $\cup$. The above Kuratowski definition of the ordered pair is "adequate" in that it satisfies the characteristic property that an ordered pair must satisfy, namely that . In particular, it adequately expresses 'order', in that is false unless .
