CCXC is written one place at a time, from the largest to the smallest: CC (200) + XC (90) = 290.

XC is the only subtraction: the X before the C takes away 10, so XC = 90.

Common mistakes

Wrong: CCLXXXX

Why isn't 290 written as CCLXXXX?

A symbol can't be repeated four times in a row. 90 is XC (100 − 10), not LXXXX, so 290 is CCXC.
