# 659 in Roman numerals

**659 in Roman numerals: DCLIX**

659 is written DCLIX in Roman numerals. That is 4 symbol groups added together, reading left to right from the largest value down.

## How it breaks down

*DCLIX = 500 + 100 + 50 + 9 = 659*

| Group | Value | Subtraction | Running total |
| --- | --- | --- | --- |
| D | 500 | — | 500 |
| C | 100 | — | 600 |
| L | 50 | — | 650 |
| IX | 9 | X − I | 659 |

## Why the smaller symbol comes first

DCLIX uses subtractive notation in one place: IX means X minus I, or 9. 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 | yes — 1× |
| C | 100 | yes — 1× |
| D | 500 | yes — 1× |
| M | 1,000 | no |
