Common mistakes
Wrong: MCMLXV1
Is MCMLXV1 the same as MCMLXVI?
No. MCMLXV1 has the digit 1 where the letter I should be, so it isn't a Roman numeral. The year is MCMLXVI.
Wrong: MCMLXIV
Is MCMLXIV also 1966?
No. Swapping the last two letters puts the smaller symbol first, so it subtracts: MCMLXIV is 1964.
Wrong: MDCCCCLXVI
Why not MDCCCCLXVI?
A symbol repeats at most three times in a row. The standard form uses subtraction: MCMLXVI.
