# 1,040 in Roman numerals

**1,040 in Roman numerals: MXL**

1,040 is written MXL in Roman numerals. That is 2 symbol groups added together, reading left to right from the largest value down.

## How it breaks down

*MXL = 1000 + 40 = 1,040*

| Group | Value | Subtraction | Running total |
| --- | --- | --- | --- |
| M | 1,000 | — | 1,000 |
| XL | 40 | L − X | 1,040 |

## Why the smaller symbol comes first

MXL uses subtractive notation in one place: XL means L minus X, or 40. 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.
