CMLI is written one place at a time, from the largest to the smallest: CM (900) + L (50) + I (1) = 951.

CM is the only subtraction: the C before the M takes away 100, so CM = 900.

Common mistakes

Wrong: DCCCCLI

Why isn't 951 written as DCCCCLI?

A symbol can't be repeated four times in a row. 900 is CM (1000 − 100), not DCCCC, so 951 is CMLI.
