**301 in Roman numerals: CCCI**

301 is written CCCI in Roman numerals. That is 4 symbol groups added together, reading left to right from the largest value down.

## How it breaks down

*CCCI = 100 + 100 + 100 + 1 = 301*

| Group | Value | Subtraction | Running total |
| --- | --- | --- | --- |

| C | 100 | — | 200 |
| C | 100 | — | 300 |

## No subtraction needed

CCCI 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.
