Roman numeral Writing Guidelines

When writing a number in Roman numerals, specific criteria must be adhered to. Please review the following rules.

As many times as the symbol is repeated, its value is added to itself. (For instance, II-2, XX-20, and XX-30).

Only three times can a symbol be repeated; for example, XXX = 30, CC = 200, etc.

The symbols V, L, and D are unique.

When a symbol with a lower value follows one with a higher value, their values will be added. As an illustration, VI = V + I = 5 + 1 = 6.

When a symbol with a lower value precedes one with a higher value, the lower value symbol will be removed. As an illustration, IX = X - I = 10 - 1 = 9.

V, L, and D are never deducted since they are not put before a sign of a higher value.

Only the symbols V and X can be subtracted from, and only the symbols L, M, and C can be subtracted from the sign I.
