Common mistakes
Wrong: DCCXXXXIV
Why isn't 744 written as DCCXXXXIV?
A symbol can't be repeated four times in a row. 40 is XL (50 − 10), not XXXX, so 744 is DCCXLIV.
Wrong: DCCXLIIII
Why isn't 744 written as DCCXLIIII?
A symbol can't be repeated four times in a row. 4 is IV (5 − 1), not IIII, so 744 is DCCXLIV.
Wrong: DCCXXXXIIII
Why isn't 744 written as DCCXXXXIIII?
No symbol can be repeated four times in a row, so XXXX and IIII are not used: 40 = XL, 4 = IV. Together they make DCCXLIV.
