# How to Read Roman Numbers and Convert from Arabic to Roman?

The Roman numerals are represented by the following letters:
• I = 1
• V = 5
• X = 10
• L = 50
• C = 100
• D = 500
• M = 1000
If a numeral is followed by another numeral of lower denomination, the two are added together. If it is preceded by one of lower denomination, the smaller numeral is subtracted from the greater.

Thus XI = 11 (X + I), but IX = 9 (X – I).

Other examples are XXC = 80, CXL = 140, XV = 15, XLVIII = 48.

Thousands from 1000 to 9000 are represented as M, MM, MMM, MMMM, MMMMM, MMMMMM, MMMMMMM, MMMMMMMM, MMMMMMMMM.

Multiples of a thousand are also/alternatively indicated by a superior bar: thus, V̅ = 5000, V̅I̅ = 6000, V̅I̅I̅ = 7000, ... , X̅ = 10000, X̅X̅D̅ = 480000, etc.
