MMMDCXL is written one place at a time, from the largest to the smallest: MMM (3000) + DC (600) + XL (40) = 3640.

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

Common mistakes

Wrong: MMMDCXXXX

Why isn't 3640 written as MMMDCXXXX?

A symbol can't be repeated four times in a row. 40 is XL (50 − 10), not XXXX, so 3640 is MMMDCXL.
