# 1,418 in Roman numerals

**1,418 in Roman numerals: MCDXVIII**

1,418 is written MCDXVIII in Roman numerals. That is 7 symbol groups added together, reading left to right from the largest value down.

## How it breaks down

*MCDXVIII = 1000 + 400 + 10 + 5 + 1 + 1 + 1 = 1,418*

| Group | Value | Subtraction | Running total |
| --- | --- | --- | --- |
| M | 1,000 | — | 1,000 |
| CD | 400 | D − C | 1,400 |
| X | 10 | — | 1,410 |
| V | 5 | — | 1,415 |
| I | 1 | — | 1,416 |
| I | 1 | — | 1,417 |
| I | 1 | — | 1,418 |

## Why the smaller symbol comes first

MCDXVIII 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.
