# 849 in Roman numerals

**849 in Roman numerals: DCCCXLIX**

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

## How it breaks down

*DCCCXLIX = 500 + 100 + 100 + 100 + 40 + 9 = 849*

| Group | Value | Subtraction | Running total |
| --- | --- | --- | --- |
| D | 500 | — | 500 |
| C | 100 | — | 600 |
| C | 100 | — | 700 |
| C | 100 | — | 800 |
| XL | 40 | L − X | 840 |
| IX | 9 | X − I | 849 |

## Why the smaller symbol comes first

DCCCXLIX uses subtractive notation in 2 places: XL means L minus X, or 40; 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
