Roman numerals are a numeral system that originated in ancient Rome and remained the standard way of writing numbers throughout Europe well into the Late Middle Ages. They use combinations of letters from the Latin alphabet (I, V, X, L, C, D, and M) to represent values.

This system was developed by the Romans around 500 BC and is still used today in many contexts, including movie sequels, book chapters, clock faces, and formal events.

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