# 1,504 in Roman numerals

**1,504 in Roman numerals: MDIV**

1,504 is written MDIV in Roman numerals. That is 3 symbol groups added together, reading left to right from the largest value down.

## How it breaks down

*MDIV = 1000 + 500 + 4 = 1,504*

| Group | Value | Subtraction | Running total |
| --- | --- | --- | --- |
| M | 1,000 | — | 1,000 |
| D | 500 | — | 1,500 |
| IV | 4 | V − I | 1,504 |

## Why the smaller symbol comes first

MDIV uses subtractive notation in one place: IV means V minus I, or 4. 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.
