MMMDCLIX is written one place at a time, from the largest to the smallest: MMM (3000) + DC (600) + L (50) + IX (9) = 3659.

IX is the only subtraction: the I before the X takes away 1, so IX = 9.

Common mistakes

Wrong: MMMDCLVIIII

Why isn't 3659 written as MMMDCLVIIII?

A symbol can't be repeated four times in a row. 9 is IX (10 − 1), not VIIII, so 3659 is MMMDCLIX.
