DCCCXC is written one place at a time, from the largest to the smallest: DCCC (800) + XC (90) = 890.

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

Common mistakes

Wrong: DCCCLXXXX

Why isn't 890 written as DCCCLXXXX?

A symbol can't be repeated four times in a row. 90 is XC (100 − 10), not LXXXX, so 890 is DCCCXC.

Wrong: CCMXC

Why isn't 890 written as CCMXC?

Only one smaller symbol can stand before a larger one, so CCM doesn't work. 800 is DCCC (500 + 300), so 890 is DCCCXC.
