Numbers, numerals & digits

Three words people mix up — the number is the idea, the numeral is how we write it, the digit is one of its symbols.

Number

The idea, the amount.

the count of fingers on two hands

Numeral

How the number is written.

10, X, 一〇

Digit

One symbol inside a numeral.

1 and 0 are the digits in 10

Why the difference matters

The numeral 10 uses two digits (1 and 0) to represent the number ten. In Roman numerals, the same number is written X — one symbol, no zero. Same number, different writing.
