MMMDCCCXLIII is written one place at a time, from the largest to the smallest: MMM (3000) + DCCC (800) + XL (40) + III (3) = 3843.

XL is the only subtraction: the X before the L takes away 10, so XL = 40.

Common mistakes

Wrong: MMMDCCCXXXXIII

Why isn't 3843 written as MMMDCCCXXXXIII?

A symbol can't be repeated four times in a row. 40 is XL (50 − 10), not XXXX, so 3843 is MMMDCCCXLIII.

Wrong: MMMCCMXLIII

Why isn't 3843 written as MMMCCMXLIII?

Only one smaller symbol can stand before a larger one, so CCM doesn't work. 800 is DCCC (500 + 300), so 3843 is MMMDCCCXLIII.
