Common mistakes
Wrong: MMMCCCCLXXXIX
Why isn't 3489 written as MMMCCCCLXXXIX?
A symbol can't be repeated four times in a row. 400 is CD (500 − 100), not CCCC, so 3489 is MMMCDLXXXIX.
Wrong: MMMCDLXXXVIIII
Why isn't 3489 written as MMMCDLXXXVIIII?
A symbol can't be repeated four times in a row. 9 is IX (10 − 1), not VIIII, so 3489 is MMMCDLXXXIX.
Wrong: MMMCCCCLXXXVIIII
Why isn't 3489 written as MMMCCCCLXXXVIIII?
No symbol can be repeated four times in a row, so CCCC and VIIII are not used: 400 = CD, 9 = IX. Together they make MMMCDLXXXIX.
