Common mistakes
Wrong: MMCCCCXXIX
Why isn't 2429 written as MMCCCCXXIX?
A symbol can't be repeated four times in a row. 400 is CD (500 − 100), not CCCC, so 2429 is MMCDXXIX.
Wrong: MMCDXXVIIII
Why isn't 2429 written as MMCDXXVIIII?
A symbol can't be repeated four times in a row. 9 is IX (10 − 1), not VIIII, so 2429 is MMCDXXIX.
Wrong: MMCCCCXXVIIII
Why isn't 2429 written as MMCCCCXXVIIII?
No symbol can be repeated four times in a row, so CCCC and VIIII are not used: 400 = CD, 9 = IX. Together they make MMCDXXIX.
