Which letters are used in Roman numerals?
Roman numerals were invented by the Romans as a counting system to make trading goods easier. So which letters did they choose to represent numbers? Well, the Romans used seven different letters to represent seven numbers.
- I = 1
- V = 5
- X = 10
- L = 50
- C = 100
- D = 500
- M = 1000
These letters are then combined to make other numbers. For example, the number 18 is made accordingly: X (10) + V (5) + III (3).
