# 3,455 in Roman numerals

**3,455 in Roman numerals: MMMCDLV**

3,455 is written MMMCDLV in Roman numerals. That is 6 symbol groups added together, reading left to right from the largest value down.

## How it breaks down

*MMMCDLV = 1000 + 1000 + 1000 + 400 + 50 + 5 = 3,455*

| Group | Value | Subtraction | Running total |
| --- | --- | --- | --- |
| M | 1,000 | — | 1,000 |
| M | 1,000 | — | 2,000 |
| M | 1,000 | — | 3,000 |
| CD | 400 | D − C | 3,400 |
| L | 50 | — | 3,450 |
| V | 5 | — | 3,455 |

## Why the smaller symbol comes first

MMMCDLV uses subtractive notation in one place: CD means D minus C, or 400. 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
