MMDCXLIII is written one place at a time, from the largest to the smallest: MM (2000) + DC (600) + XL (40) + III (3) = 2643.

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

Common mistakes

Wrong: MMDCXXXXIII

Why isn't 2643 written as MMDCXXXXIII?

A symbol can't be repeated four times in a row. 40 is XL (50 − 10), not XXXX, so 2643 is MMDCXLIII.
