Total742DCCXLII

DCCXLII is written one place at a time, from the largest to the smallest: DCC (700) + XL (40) + II (2) = 742.

XL is the only subtraction: the X before the L takes away 10, so XL = 40.

Common mistakes

Wrong: DCCXXXXII

Why isn't 742 written as DCCXXXXII?

A symbol can't be repeated four times in a row. 40 is XL (50 − 10), not XXXX, so 742 is DCCXLII.
