# 947 in Roman numerals

**947 in Roman numerals: CMXLVII**

947 is written CMXLVII in Roman numerals. That is 5 symbol groups added together, reading left to right from the largest value down.

## How it breaks down

*CMXLVII = 900 + 40 + 5 + 1 + 1 = 947*

| Group | Value | Subtraction | Running total |
| --- | --- | --- | --- |
| CM | 900 | M − C | 900 |
| XL | 40 | L − X | 940 |
| V | 5 | — | 945 |
| I | 1 | — | 946 |
| I | 1 | — | 947 |

## Why the smaller symbol comes first

CMXLVII uses subtractive notation in 2 places: CM means M minus C, or 900; 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

| Symbol | Value | Used here |

| L | 50 | yes — 1× |
| C | 100 | yes — 1× |
