Common mistakes

Wrong: MCMXV11

Is MCMXV11 the same as MCMXVII?

No. MCMXV11 has the digit 1 where the letter I should be, so it isn't a Roman numeral. The year is MCMXVII.

Wrong: MDCCCCXVII

Why not MDCCCCXVII?

A symbol repeats at most three times in a row. The standard form uses subtraction: MCMXVII.
