# 289 in Roman numerals

**289 in Roman numerals: CCLXXXIX**

289 is written CCLXXXIX in Roman numerals. That is 7 symbol groups added together, reading left to right from the largest value down.

## How it breaks down

*CCLXXXIX = 100 + 100 + 50 + 10 + 10 + 10 + 9 = 289*

| Group | Value | Subtraction | Running total |
| --- | --- | --- | --- |
| C | 100 | — | 100 |
| C | 100 | — | 200 |
| L | 50 | — | 250 |
| X | 10 | — | 260 |
| X | 10 | — | 270 |
| X | 10 | — | 280 |
| IX | 9 | X − I | 289 |

## Why the smaller symbol comes first

CCLXXXIX uses subtractive notation in one place: IX means X minus I, or 9. 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 | yes — 1× |
| C | 100 | yes — 2× |
| D | 500 | no |
