# 414 in Roman numerals

**414 in Roman numerals: CDXIV**

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

## How it breaks down

*CDXIV = 400 + 10 + 4 = 414*

| Group | Value | Subtraction | Running total |
| --- | --- | --- | --- |
| CD | 400 | D − C | 400 |
| X | 10 | — | 410 |
| IV | 4 | V − I | 414 |

## Why the smaller symbol comes first

CDXIV uses subtractive notation in 2 places: CD means D minus C, or 400; 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

| L | 50 | no |
| C | 100 | yes — 1× |
| D | 500 | yes — 1× |
