DXL is written one place at a time, from the largest to the smallest: D (500) + XL (40) = 540.

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

Common mistakes

Wrong: DXXXX

Why isn't 540 written as DXXXX?

A symbol can't be repeated four times in a row. 40 is XL (50 − 10), not XXXX, so 540 is DXL.
