WebMay 8, 2024 · Definition. The definition of a set does not take any account of the order in which the elements are listed. That is, { a, b } = { b, a }, and the elements a and b have the same status - neither is distinguished above the other as being more "important". The concept of an ordered pair can be formalized by the definition: 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 }.

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. WebA set theory does not only express theorems about numbers, and so one may consider a more general so-called strong existence property that is harder to come by, as will be discussed. ...

Webthen we use a different object called ordered pair, represented (a,b). Now (a,b) 6= (b,a) (unless a = b). In general (a,b) = (a0,b0) iff a = a0 and b = b0. Given two sets A, B, their … sic trap
