Total247CCXLVII

CCXLVII is written one place at a time, from the largest to the smallest: CC (200) + XL (40) + VII (7) = 247.

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

Common mistakes

Wrong: CCXXXXVII

Why isn't 247 written as CCXXXXVII?

A symbol can't be repeated four times in a row. 40 is XL (50 − 10), not XXXX, so 247 is CCXLVII.
