# 3,974 in Roman numerals

**3,974 in Roman numerals: MMMCMLXXIV**

3,974 is written MMMCMLXXIV in Roman numerals. That is 8 symbol groups added together, reading left to right from the largest value down.

## How it breaks down

*MMMCMLXXIV = 1000 + 1000 + 1000 + 900 + 50 + 10 + 10 + 4 = 3,974*

| Group | Value | Subtraction | Running total |
| --- | --- | --- | --- |
| M | 1,000 | — | 1,000 |
| M | 1,000 | — | 2,000 |
| M | 1,000 | — | 3,000 |
| CM | 900 | M − C | 3,900 |
| L | 50 | — | 3,950 |
| X | 10 | — | 3,960 |
| X | 10 | — | 3,970 |
| IV | 4 | V − I | 3,974 |

## Why the smaller symbol comes first

MMMCMLXXIV uses subtractive notation in 2 places: CM means M minus C, or 900; 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
