Total436CDXXXVI

CDXXXVI is written one place at a time, from the largest to the smallest: CD (400) + XXX (30) + VI (6) = 436.

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

Common mistakes

Wrong: CCCCXXXVI

Why isn't 436 written as CCCCXXXVI?

A symbol can't be repeated four times in a row. 400 is CD (500 − 100), not CCCC, so 436 is CDXXXVI.
