# Different Types of Numbers

Cardinal numbers are counting numbers. Ordinal numbers tell us about position. Nominal numbers are just names: they don't have any value or position.

## Cardinal numbers

The cardinal numbers are the counting numbers. They are **whole** numbers that tell you how many of something there are. So, they don't include fractions
or decimals. For example, you would
use a cardinal number to describe the number of brussels sprouts that are on your plate at the start of dinner (hopefully, \(0\)!). In the picture below,
there are **six** coins. Six is a cardinal number.

**count**things.

## Ordinal Numbers

How do we describe the position of something in a race, a line or a list? Using an ordinal number. Ordinal numbers tell us about position. They
are things like **1st** (or **first**), **2nd**(or **second**), **3rd** (or **third**)
**4th** (or **fourth**), **5th** (or **fifth**) and **6th** (or **sixth**), etc. For example, the snails in the picture below are having a race.

**1st**position. The green and yellow snail is coming

**second**, the red and brown snail is coming

**third**and the brown and yellow snail is coming last. As there are only four snails in the race, he is in

**4th**position.

**order**that things are in.

## Nominal Numbers

These are just numbers that are used as **names**. For example, the car in the picture below is given the number \(453\) as a name. This
name tells us nothing about how many cars there are or the position of the car in a race.

- The number on a cricketer's shirt. Nathan Lyon wore shirt number 67 in 2016.
- A post code: Melbourne's post code is 3000.
- A lego set number such as 75192.

**name**things.
