# 210 in Roman numerals

**210 in Roman numerals: CCX**

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

## How it breaks down

*CCX = 100 + 100 + 10 = 210*

| --- | --- | --- | --- |
| C | 100 | — | 100 |
| C | 100 | — | 200 |

## No subtraction needed

CCX 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.
