What Are Roman Numerals?

Roman numerals originated in ancient Rome and were used throughout the Roman Empire for counting, trade, and inscriptions.

Instead of using the digits we know today (0-9), Romans used a combination of letters:

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

For example:

• XII = 12
• XIX = 19
• MMXX = 2020

Roman numerals are still widely used in modern life for clocks, monarch names (Queen Elizabeth II), outlines, and special events.
