# 297 in Roman numerals

**297 in Roman numerals: CCXCVII**

297 is written CCXCVII in Roman numerals. That is 6 symbol groups added together, reading left to right from the largest value down.

## How it breaks down

*CCXCVII = 100 + 100 + 90 + 5 + 1 + 1 = 297*

| Group | Value | Subtraction | Running total |
| --- | --- | --- | --- |
| C | 100 | — | 100 |
| C | 100 | — | 200 |
| XC | 90 | C − X | 290 |
| V | 5 | — | 295 |
| I | 1 | — | 296 |
| I | 1 | — | 297 |

## Why the smaller symbol comes first

CCXCVII uses subtractive notation in one place: XC means C minus X, or 90. A smaller symbol placed before a larger one is subtracted from it rather than added, which is why IX is nine and not eleven.

Only six such pairs are valid — IV, IX, XL, XC, CD and CM. That restriction is what makes the notation unambiguous: IIII and IC both look like they should work, but neither is standard, and only one spelling of any number is correct.

## The symbols

| L | 50 | no |
| C | 100 | yes — 3× |
| D | 500 | no |
