# Numbers, Numerals and Digits

## Number

A number is a count or measurement that is really an idea in our minds.

We write or talk about numbers using numerals such as "4" or "four".

But we could also hold up 4 fingers, or tap the ground 4 times.

These are all different ways of referring to the same number.

There are also special numbers (like π (Pi)) that can't be written exactly, but are still numbers because we know the idea behind them.

## Numeral

A numeral is a symbol or name that stands for a number.

Examples: 3, 49 and twelve are all numerals.

So the number is an idea, the numeral is how we write it.

## Digit

A digit is a single symbol used to make numerals.

0, 1, 2, 3, 4, 5, 6, 7, 8 and 9 are the ten digits we use in everyday numerals.

Example: The numeral 153 is made up of 3 digits ("1", "5" and "3").

Example: The numeral 46 is made up of 2 digits ("4", and "6").

Example: The numeral 9 is made up of 1 digit ("9"). So a single digit can also be a numeral

## Digits -> Numerals -> Numbers

So digits make up numerals, and numerals stand for an idea of a number.

Just like letters make up words, and words stand for an idea of the thing.
