Common mistakes
Wrong: MCM1X
Is MCM1X the same as MCMIX?
No. MCM1X has the digit 1 where the letter I should be, so it isn't a Roman numeral. The year is MCMIX.
Wrong: MCMXI
Is MCMXI also 1909?
No. Swapping the last two letters turns a subtraction into an addition: MCMXI is 1911.
Wrong: MDCCCCIX
Why not MDCCCCIX?
A symbol repeats at most three times in a row. The standard form uses subtraction: MCMIX.
