What Is a Roman Numeral?
A Roman numeral is a number represented using letters from the Latin alphabet. The seven basic Roman numeral symbols are:
Symbol| Value
I| 1
V| 5
X| 10
L| 50
C| 100
D| 500
M| 1000
These symbols can be combined to represent larger numbers. For example:
- XIV = 14
- XXIV = 24
- XLIX = 49
- XCIX = 99
- MCMXC = 1990
How Roman Numerals Work
Roman numerals follow two main rules:
Addition Rule
When a smaller or equal numeral appears after another numeral, the values are added together.
Examples:
- VI = 6 (5 + 1)
- XV = 15 (10 + 5)
- XX = 20 (10 + 10)
Subtraction Rule
When a smaller numeral appears before a larger numeral, the smaller value is subtracted.
Examples:
- IV = 4 (5 − 1)
- IX = 9 (10 − 1)
- XL = 40 (50 − 10)
- XC = 90 (100 − 10)
- CD = 400 (500 − 100)
- CM = 900 (1000 − 100)
How to Convert Roman Numerals to Numbers
Converting Roman numerals to numbers manually requires understanding the addition and subtraction rules.
For example:
Roman Numeral: MCMXC
Breakdown:
- M = 1000
- CM = 900
- XC = 90
Total:
1000 + 900 + 90 = 1990
