## Introduction

The cookies are kept in the $$3^\text{rd}$$ drawer from the top.
The orange dress is the $$7^\text{th}$$ one from the right.
The football is kept in the $$3^\text{rd}$$ carton box from the left.

All these sentences have one thing in common.
They all talk about the position of certain objects (cookies, orange dress, football).

This is the main element in the discussion of ordinal numbers.

## Ordinal Numbers

An ordinal number tells the numerical position of an object in a list. In other words, it indicates the order of things or objects, such as first, second, third, fourth, and so on.

An ordinal number usually ends in “th.”
