How it breaks down
| Group | Value | Subtraction | Running total |
|---|---|---|---|
| D | 500 | — | 500 |
| C | 100 | — | 600 |
| C | 100 | — | 700 |
| C | 100 | — | 800 |

Why the smaller symbol comes first
DCCCLXIX 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.
