# 834 in Roman numerals

**834 in Roman numerals: DCCCXXXIV**

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

## How it breaks down

*DCCCXXXIV = 500 + 100 + 100 + 100 + 10 + 10 + 10 + 4 = 834*

| Group | Value | Subtraction | Running total |
| --- | --- | --- | --- |
| D | 500 | — | 500 |
| C | 100 | — | 600 |
| C | 100 | — | 700 |
| C | 100 | — | 800 |
| X | 10 | — | 810 |
| X | 10 | — | 820 |
| X | 10 | — | 830 |
| IV | 4 | V − I | 834 |

## Why the smaller symbol comes first

DCCCXXXIV 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
