# 300 in Roman numerals

**300 in Roman numerals: CCC**

300 is written CCC in Roman numerals. That is 3 symbol groups added together, reading left to right from the largest value down.

## How it breaks down

*CCC = 100 + 100 + 100 = 300*

| Group | Value | Subtraction | Running total |
| --- | --- | --- | --- |
| C | 100 | — | 100 |
| C | 100 | — | 200 |
| C | 100 | — | 300 |

## No subtraction needed

CCC is purely additive — every symbol is simply added to the one before it, with no subtractive pairs like IV or IX. Numbers avoid subtraction when none of their digits is a 4 or a 9.
