CMX is written one place at a time, from the largest to the smallest: CM (900) + X (10) = 910.

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

Common mistakes

Wrong: DCCCCX

Why isn't 910 written as DCCCCX?

A symbol can't be repeated four times in a row. 900 is CM (1000 − 100), not DCCCC, so 910 is CMX.
