# 2,449 in Roman numerals

**2,449 in Roman numerals: MMCDXLIX**

2,449 is written MMCDXLIX in Roman numerals. That is 5 symbol groups added together, reading left to right from the largest value down.

## How it breaks down

*MMCDXLIX = 1000 + 1000 + 400 + 40 + 9 = 2,449*

| Group | Value | Subtraction | Running total |
| --- | --- | --- | --- |
| M | 1,000 | — | 1,000 |
| M | 1,000 | — | 2,000 |
| CD | 400 | D − C | 2,400 |
| XL | 40 | L − X | 2,440 |
| IX | 9 | X − I | 2,449 |

## Why the smaller symbol comes first

MMCDXLIX uses subtractive notation in 3 places: CD means D minus C, or 400; 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
