The seven symbols
| Symbol | Value |
|---|---|
| I | 1 |
| V | 5 |
| X | 10 |
| L | 50 |
| C | 100 |
| D | 500 |
| M | 1000 |
Every Roman numeral is built from these seven letters. Values are added from left to right, unless a smaller symbol comes before a larger one, in which case it is subtracted.
The rules in short
- Symbols are written from largest to smallest, left to right.
- I, X, C and M can repeat up to three times in a row; V, L and D never repeat.
- Subtract by placing a smaller symbol before a larger one, but only I before V or X, X before L or C, and C before D or M.
- Standard Roman numerals stop at 3999 (MMMCMXCIX), because there is no symbol for 5000 in the standard system.
- There is no symbol for zero.
