# 455 in Roman numerals

**455 in Roman numerals: CDLV**

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

## How it breaks down

*CDLV = 400 + 50 + 5 = 455*

| Group | Value | Subtraction | Running total |
| --- | --- | --- | --- |
| CD | 400 | D − C | 400 |
| L | 50 | — | 450 |
| V | 5 | — | 455 |

## Why the smaller symbol comes first

CDLV 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

| Symbol | Value | Used here |

| V | 5 | yes — 1× |
| X | 10 | no |
| L | 50 | yes — 1× |
| C | 100 | yes — 1× |
| D | 500 | yes — 1× |
| M | 1,000 | no |
