# 46 in Roman numerals

**46 in Roman numerals: 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

*XLVI = 40 + 5 + 1 = 46*

| 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.

## The symbols

| L | 50 | yes — 1× |
| C | 100 | no |
| D | 500 | no |
