CMXLIII is written one place at a time, from the largest to the smallest: CM (900) + XL (40) + III (3) = 943.

CM and XL are subtractive pairs: in each one the smaller symbol comes first and is taken away.

Common mistakes

Wrong: DCCCCXLIII

Why isn't 943 written as DCCCCXLIII?

A symbol can't be repeated four times in a row. 900 is CM (1000 − 100), not DCCCC, so 943 is CMXLIII.

Wrong: CMXXXXIII

Why isn't 943 written as CMXXXXIII?

A symbol can't be repeated four times in a row. 40 is XL (50 − 10), not XXXX, so 943 is CMXLIII.

Wrong: DCCCCXXXXIII

Why isn't 943 written as DCCCCXXXXIII?

No symbol can be repeated four times in a row, so DCCCC and XXXX are not used: 900 = CM, 40 = XL. Together they make CMXLIII.
