# 1,229 in Roman numerals

**1,229 in Roman numerals: MCCXXIX**

1,229 is written MCCXXIX in Roman numerals. That is 6 symbol groups added together, reading left to right from the largest value down.

## How it breaks down

*MCCXXIX = 1000 + 100 + 100 + 10 + 10 + 9 = 1,229*

| Group | Value | Subtraction | Running total |
| --- | --- | --- | --- |
| M | 1,000 | — | 1,000 |
| C | 100 | — | 1,100 |
| C | 100 | — | 1,200 |
| X | 10 | — | 1,210 |
| X | 10 | — | 1,220 |
| IX | 9 | X − I | 1,229 |

## Why the smaller symbol comes first

MCCXXIX 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.
