What Are Roman Numerals?
Roman numerals use letters from the Latin alphabet to represent values. They are made of seven core symbols:
| Symbol | Value | Example |
|---|---|---|
| I | 1 | I = 1 |
| V | 5 | VI = 6 |
| X | 10 | IV = 4 |
| L | 50 | XL = 40 |
| C | 100 | XC = 90 |
| D | 500 | CD = 400 |
| M | 1000 | CM = 900 |
- VI = 6 = 5+1
- IV = 4 = 5-1
- XL = 40 = 50-10
- XC = 90 = 100-10
- 100 in Roman numerals = C
