How Roman Numerals Work

Roman numerals are a numeral system originating in ancient Rome that uses combinations of letters from the Latin alphabet. The system remained the standard way of writing numbers in Europe well into the late Middle Ages, and is still used today for clock faces, Super Bowl numbering, book chapters, and formal documents.

The Seven Core Symbols

I
= 1
V
= 5
X
= 10
L
= 50
C
= 100
D
= 500
M
= 1000

Additive and Subtractive Notation

When a smaller symbol appears before a larger one, it is subtracted. For example, IV = 4 (5 − 1) and IX = 9 (10 − 1). This subtractive rule applies only for the six pairs: IV, IX, XL, XC, CD, and CM. All other combinations are additive — symbols are simply summed from left to right.

Repetition Rules

The symbols I, X, C, and M may each be repeated up to three times in a row. V, L, and D are never repeated. This means 3 = III, 30 = XXX, and 3000 = MMM — but 4 is not IIII; it is IV.

Valid Range

Standard Roman numerals cover 1 through 3999. The number 3999 is MMMCMXCIX — the largest expressible without an overline extension. The number 1 is simply I.
