Common mistakes
Wrong: MMMCCCCXXXIX

Wrong: MMMCDXXXVIIII
Why isn't 3439 written as MMMCDXXXVIIII?
A symbol can't be repeated four times in a row. 9 is IX (10 − 1), not VIIII, so 3439 is MMMCDXXXIX.
Wrong: MMMCCCCXXXVIIII

No symbol can be repeated four times in a row, so CCCC and VIIII are not used: 400 = CD, 9 = IX. Together they make MMMCDXXXIX.
