Common mistakes
Wrong: MMMCXXXXIV
Why isn't 3144 written as MMMCXXXXIV?
A symbol can't be repeated four times in a row. 40 is XL (50 − 10), not XXXX, so 3144 is MMMCXLIV.
Wrong: MMMCXLIIII
Why isn't 3144 written as MMMCXLIIII?
A symbol can't be repeated four times in a row. 4 is IV (5 − 1), not IIII, so 3144 is MMMCXLIV.
Wrong: MMMCXXXXIIII
Why isn't 3144 written as MMMCXXXXIIII?
No symbol can be repeated four times in a row, so XXXX and IIII are not used: 40 = XL, 4 = IV. Together they make MMMCXLIV.
