539 is written DXXXIX in Roman numerals. That is 5 symbol groups added together, reading left to right from the largest value down.
How it breaks down
| Group | Value | Subtraction | Running total |
|---|---|---|---|
| D | 500 | — | 500 |

| X | 10 | — | 520 |
| X | 10 | — | 530 |
| IX | 9 | X − I | 539 |
Why the smaller symbol comes first
DXXXIX 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.
