CDLVI is written one place at a time, from the largest to the smallest: CD (400) + L (50) + VI (6) = 456.

CD is the only subtraction: the C before the D takes away 100, so CD = 400.

Common mistakes

Wrong: CCCCLVI

Why isn't 456 written as CCCCLVI?

A symbol can't be repeated four times in a row. 400 is CD (500 − 100), not CCCC, so 456 is CDLVI.
