XLVII is written one place at a time, from the largest to the smallest: XL (40) + VII (7) = 47.

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

Common mistakes

Wrong: XXXXVII

Why isn't 47 written as XXXXVII?

A symbol can't be repeated four times in a row. 40 is XL (50 − 10), not XXXX, so 47 is XLVII.
