|---|---|---|---|
| C | 100 | — | 100 |
| XC | 90 | C − X | 190 |
Why the smaller symbol comes first
CXC uses subtractive notation in one place: XC means C minus X, or 90. 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.
