MCCXXXIX is written one place at a time, from the largest to the smallest: M (1000) + CC (200) + XXX (30) + IX (9) = 1239.

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

Common mistakes

Wrong: MCCXXXVIIII

Why isn't 1239 written as MCCXXXVIIII?

A symbol can't be repeated four times in a row. 9 is IX (10 − 1), not VIIII, so 1239 is MCCXXXIX.
