# 190 in Roman numerals

**190 in Roman numerals: CXC**

190 is written CXC in Roman numerals. That is 2 symbol groups added together, reading left to right from the largest value down.

## How it breaks down

*CXC = 100 + 90 = 190*

| Group | Value | Subtraction | Running total |
| --- | --- | --- | --- |
| C | 100 | — | 100 |
| XC | 90 | C − X | 190 |

## Why the smaller symbol comes first

CXC 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
