Common mistakes
Wrong: MMDXXXXIV
Why isn't 2544 written as MMDXXXXIV?
A symbol can't be repeated four times in a row. 40 is XL (50 − 10), not XXXX, so 2544 is MMDXLIV.
Wrong: MMDXLIIII
Why isn't 2544 written as MMDXLIIII?
A symbol can't be repeated four times in a row. 4 is IV (5 − 1), not IIII, so 2544 is MMDXLIV.
Wrong: MMDXXXXIIII
Why isn't 2544 written as MMDXXXXIIII?
No symbol can be repeated four times in a row, so XXXX and IIII are not used: 40 = XL, 4 = IV. Together they make MMDXLIV.
