# 198 in Roman numerals

**198 in Roman numerals: CXCVIII**

198 is written CXCVIII in Roman numerals. That is 6 symbol groups added together, reading left to right from the largest value down.

## How it breaks down

*CXCVIII = 100 + 90 + 5 + 1 + 1 + 1 = 198*

| Group | Value | Subtraction | Running total |
| --- | --- | --- | --- |
| C | 100 | — | 100 |
| XC | 90 | C − X | 190 |
| V | 5 | — | 195 |
| I | 1 | — | 196 |
| I | 1 | — | 197 |
| I | 1 | — | 198 |

## Why the smaller symbol comes first

CXCVIII uses subtractive notation in one place: 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.

## The symbols
