How to Convert to Roman Numerals

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 = 5 000, V̅I̅ = 6 000, V̅I̅I̅ = 7000, ... , X̅ = 10000, X̅X̅D̅ = 480 000, etc.
