# 1,489 in Roman numerals

**1,489 in Roman numerals: MCDLXXXIX**

1,489 is written MCDLXXXIX in Roman numerals. That is 7 symbol groups added together, reading left to right from the largest value down.

## How it breaks down

*MCDLXXXIX = 1000 + 400 + 50 + 10 + 10 + 10 + 9 = 1,489*

| Group | Value | Subtraction | Running total |
| --- | --- | --- | --- |
| M | 1,000 | — | 1,000 |
| CD | 400 | D − C | 1,400 |
| L | 50 | — | 1,450 |
| X | 10 | — | 1,460 |
| X | 10 | — | 1,470 |
| X | 10 | — | 1,480 |
| IX | 9 | X − I | 1,489 |

## Why the smaller symbol comes first

MCDLXXXIX uses subtractive notation in 2 places: CD means D minus C, or 400; 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.
