CDXXXV
435 is written CDXXXV 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 |
|---|---|---|---|
| CD | 400 | D − C | 400 |
| X | 10 | — | 410 |
| X | 10 | — | 420 |
| X | 10 | — | 430 |
| V | 5 | — | 435 |
Why the smaller symbol comes first
CDXXXV uses subtractive notation in one place: CD means D minus C, or 400. 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.
