# 1,955 in Roman numerals

**1,955 in Roman numerals: MCMLV**

1,955 is written MCMLV in Roman numerals. That is 4 symbol groups added together, reading left to right from the largest value down.

## How it breaks down

*MCMLV = 1000 + 900 + 50 + 5 = 1,955*

| Group | Value | Subtraction | Running total |
| --- | --- | --- | --- |
| M | 1,000 | — | 1,000 |
| CM | 900 | M − C | 1,900 |
| L | 50 | — | 1,950 |
| V | 5 | — | 1,955 |

## Why the smaller symbol comes first

MCMLV uses subtractive notation in one place: CM means M minus C, or 900. 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 |
| --- | --- | --- |
| I | 1 | no |
| V | 5 | yes — 1× |
| X | 10 | no |
| L | 50 | yes — 1× |
| C | 100 | yes — 1× |
| D | 500 | no |
| M | 1,000 | yes — 2× |
