How it breaks down
| Group | Value | Subtraction | Running total |
|---|---|---|---|
| M | 1,000 | — | 1,000 |
| CD | 400 | D − C | 1,400 |
| XL | 40 | L − X | 1,440 |

| I | 1 | — | 1,446 |
| I | 1 | — | 1,447 |
Why the smaller symbol comes first
MCDXLVII uses subtractive notation in 2 places: CD means D minus C, or 400; XL means L minus X, or 40. 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.
