# 1,424 in Roman numerals

**1,424 in Roman numerals: MCDXXIV**

1,424 is written MCDXXIV in Roman numerals. That is 5 symbol groups added together, reading left to right from the largest value down.

## How it breaks down

*MCDXXIV = 1000 + 400 + 10 + 10 + 4 = 1,424*

| Group | Value | Subtraction | Running total |
| --- | --- | --- | --- |
| M | 1,000 | — | 1,000 |
| CD | 400 | D − C | 1,400 |
| X | 10 | — | 1,410 |
| X | 10 | — | 1,420 |
| IV | 4 | V − I | 1,424 |

## Why the smaller symbol comes first

MCDXXIV 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.
