WebOct 20, 2012 · Ordered pairs and sets are different types of objects. For sets, {a,b}= {b,a}, while for ordered pairs (a,b)= (b,a) is false unless a=b. As a part of the programme to reduce all mathematics to set theory, one wants to define all objects as sets, so that one has only one fundamental type of object. 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:
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.

If A and B are equal, we write A = B. The following result is straightforward and very convenient for proving equality between sets. Theorem 1.1.1 Two sets A and B are equal if and only if A ⊂ B and B ⊂ A. If A ⊂ B and A does not equal B, we say that A is a proper subset of B, and write A ⊊ B.
