Total966CMLXVI

CMLXVI is written one place at a time, from the largest to the smallest: CM (900) + LX (60) + VI (6) = 966.

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

Common mistakes

Wrong: DCCCCLXVI

Why isn't 966 written as DCCCCLXVI?

A symbol can't be repeated four times in a row. 900 is CM (1000 − 100), not DCCCC, so 966 is CMLXVI.
