Roman numerals are a numeral system that originated in ancient Rome and remained the usual way of writing numbers throughout Europe well into the Late Middle Ages.
Roman numerals use seven basic symbols, each with a fixed value. These symbols are combined to represent all numbers in the Roman numeral system. Understanding these core symbols is the foundation for reading and writing any Roman numeral.
| Symbol | Value |
|---|---|
| I | 1 |
| V | 5 |
| X | 10 |
| L | 50 |
| C | 100 |
| D | 500 |
| M | 1000 |
Some Roman numerals use a subtractive principle, where a smaller symbol placed before a larger one means you subtract the smaller value from the larger. These special combinations help avoid repeating the same symbol more than three times in a row and make the numerals shorter and easier to read.
| Combination | Value |
|---|---|
| IV | 4 (5-1) |
| IX | 9 (10-1) |
| XL | 40 (50-10) |
