Common mistakes
Wrong: MMCCCCLXXIX
Why isn't 2479 written as MMCCCCLXXIX?
A symbol can't be repeated four times in a row. 400 is CD (500 − 100), not CCCC, so 2479 is MMCDLXXIX.
Wrong: MMCDLXXVIIII
Why isn't 2479 written as MMCDLXXVIIII?
A symbol can't be repeated four times in a row. 9 is IX (10 − 1), not VIIII, so 2479 is MMCDLXXIX.
Wrong: MMCCCCLXXVIIII
Why isn't 2479 written as MMCCCCLXXVIIII?
No symbol can be repeated four times in a row, so CCCC and VIIII are not used: 400 = CD, 9 = IX. Together they make MMCDLXXIX.
