How it breaks down
| Group | Value | Subtraction | Running total |

| L | 50 | — | 450 |
| X | 10 | — | 460 |

| I | 1 | — | 477 |
Why the smaller symbol comes first
CDLXXVII 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.
