Order

Pronunciation: /ˈɔr.dər/ Explain

The order of a set is how the set is sorted.[2] One example of an ordered set is the set of integers. One can always tell which of any two integers come first. For example, 1 always comes before 5.

The operators =, , <, >, , show the relative order of elements of an ordered set.

Sets other than numbers can be ordered. For example, the alphabet is an ordered set of letters. The statement 'a' < 'd' makes sense in terms of this ordering.

The points in a line are ordered. One can tell which points come before and after a particular point.
