Total798DCCXCVIII

DCCXCVIII is written one place at a time, from the largest to the smallest: DCC (700) + XC (90) + VIII (8) = 798.

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

Common mistakes

Wrong: DCCLXXXXVIII

Why isn't 798 written as DCCLXXXXVIII?

A symbol can't be repeated four times in a row. 90 is XC (100 − 10), not LXXXX, so 798 is DCCXCVIII.

Wrong: DCCXCIIX

Why isn't 798 written as DCCXCIIX?

Only one smaller symbol can stand before a larger one, so IIX doesn't work. 8 is VIII (5 + 3), so 798 is DCCXCVIII.
