# 354 in Roman numerals

**354 in Roman numerals: CCCLIV**

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

## How it breaks down

*CCCLIV = 100 + 100 + 100 + 50 + 4 = 354*

| Group | Value | Subtraction | Running total |
| --- | --- | --- | --- |
| C | 100 | — | 100 |
| C | 100 | — | 200 |
| C | 100 | — | 300 |
| L | 50 | — | 350 |
| IV | 4 | V − I | 354 |

## Why the smaller symbol comes first

CCCLIV uses subtractive notation in one place: IV means V minus I, or 4. 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 | yes — 1× |
| V | 5 | yes — 1× |
| X | 10 | no |
| L | 50 | yes — 1× |
| C | 100 | yes — 3× |
| D | 500 | no |
| M | 1,000 | no |
