A symbol can be repeated only for three times, for example XXX = 30, CC = 200, etc.

Symbols V, L, and D are never repeated.

When a symbol of smaller value appears after a symbol of greater value, its values will be added. For Example-  VI = V + I = 5 + 1 = 6.

When a symbol of a smaller value appears before a greater value symbol, it will be subtracted. For Example-  IX = X – I = 10 – 1 = 9.

The symbols V, L, and D are never subtracted, as they are not written before a greater value symbol.

The symbol I can be subtracted from V and X only and symbol X can be subtracted from symbols L, M and C only.

Converting Roman Numerals to Numbers

Rule 1: If one or more symbols are placed after another letter of greater value, add that amount.

VII = 7 (5 + 2 = 7)

LXXX = 80 (50 + 10 + 10 + 10 = 80)

MCCC = 1300 (1000+100 + 100 + 100 = 1300)

Rule 2: If a symbol is placed before another letter of greater value, subtract that amount.

CM = 900 (1000 – 100 = 900)

IX = 9 ( 10 – 1 = 9 )

XC = 90 (100 – 10 = 90)
