Common mistakes

Wrong: MMMCCCCXL

Why isn't 3440 written as MMMCCCCXL?

A symbol can't be repeated four times in a row. 400 is CD (500 − 100), not CCCC, so 3440 is MMMCDXL.

Wrong: MMMCDXXXX

Why isn't 3440 written as MMMCDXXXX?

A symbol can't be repeated four times in a row. 40 is XL (50 − 10), not XXXX, so 3440 is MMMCDXL.

Wrong: MMMCCCCXXXX

Why isn't 3440 written as MMMCCCCXXXX?

No symbol can be repeated four times in a row, so CCCC and XXXX are not used: 400 = CD, 40 = XL. Together they make MMMCDXL.
