DXXIV
524 is written DXXIV in Roman numerals. That is 4 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 | — | 510 |
| X | 10 | — | 520 |
| IV | 4 | V − I | 524 |
Why the smaller symbol comes first
DXXIV 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.
