Understanding Roman Numerals

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. The system uses combinations of letters from the Latin alphabet to signify values. The basic symbols are:

I = 1

X = 10
L = 50
C = 100
D = 500
M = 1000

These symbols can be combined to represent larger numbers. For example, IV represents 4, IX represents 9, and XL represents 40. The Roman numeral seven, VII, is formed by combining V (5) and two I’s (1 + 1), resulting in 7.
