Ordered pair set theory

WebThe set T is defined as T = { (i, j) i, j ∈ Natural Numbers }, which means it contains all ordered pairs (i, j) where i and j are natural numbers. To show that T is countable, we need to show that there exists a one-to-one correspondence between T and the set of natural numbers. One possible way to do this is to use a diagonalization argument. WebMath 1 20 (Nataro) A fraction is an ordered pair of whole numbers (a, b) where b 6= 0. The set of fractions is the set F = n a b fl fl fl a, b are whole numbers and b 6= 0 o Here a is referred to as the numerator and b is referred to as the denominator. A fraction is ONE number that represents a relationship between two numbers! Two fractions ...

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 }. Web1.1Ordered pairs and Cartesian products • The elements of a set are not ordered.

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. 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.
