# 1,998 in Roman numerals

**1,998 in Roman numerals: MCMXCVIII**

1,998 is written MCMXCVIII in Roman numerals. That is 7 symbol groups added together, reading left to right from the largest value down.

## How it breaks down

*MCMXCVIII = 1000 + 900 + 90 + 5 + 1 + 1 + 1 = 1,998*

| Group | Value | Subtraction | Running total |
| --- | --- | --- | --- |
| M | 1,000 | — | 1,000 |
| CM | 900 | M − C | 1,900 |
| XC | 90 | C − X | 1,990 |
| V | 5 | — | 1,995 |
| I | 1 | — | 1,996 |
| I | 1 | — | 1,997 |
| I | 1 | — | 1,998 |

## Why the smaller symbol comes first

MCMXCVIII uses subtractive notation in 2 places: CM means M minus C, or 900; XC means C minus X, or 90. 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.
