XLVI
46 is written XLVI in Roman numerals. That is 3 symbol groups added together, reading left to right from the largest value down.
How it breaks down
| Group | Value | Subtraction | Running total |
|---|---|---|---|
| XL | 40 | L − X | 40 |
| V | 5 | — | 45 |
| I | 1 | — | 46 |
Why the smaller symbol comes first
XLVI uses subtractive notation in one place: 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.
