MDCXXIX is written one place at a time, from the largest to the smallest: M (1000) + DC (600) + XX (20) + IX (9) = 1629.

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

Common mistakes

Wrong: MDCXXVIIII

Why isn't 1629 written as MDCXXVIIII?

A symbol can't be repeated four times in a row. 9 is IX (10 − 1), not VIIII, so 1629 is MDCXXIX.
