# Ordinal Numbers

## NUMBERS AND OPERATIONS

An ordinal number is one that indicates the position or order that an element occupies in a set.

The cardinal numbers (1, 2, 3) are used to quantify the size of a set (either finite or infinite), while the ordinal numbers (1st, 2nd, 3rd) are used to describe the position of an element in a sequence (finite or infinite).

We provide you the explanation so that you can easily learn what ordinal numbers from 1st to 10th are... From an exciting ostrich race! In addition, you will understand how they differ from cardinal numbers and how to read and write them correctly.
