CDXCVI is written one place at a time, from the largest to the smallest: CD (400) + XC (90) + VI (6) = 496.
CD and XC are subtractive pairs: in each one the smaller symbol comes first and is taken away.
Common mistakes
Wrong: CCCCXCVI
Why isn't 496 written as CCCCXCVI?
A symbol can't be repeated four times in a row. 400 is CD (500 − 100), not CCCC, so 496 is CDXCVI.
Wrong: CDLXXXXVI
Why isn't 496 written as CDLXXXXVI?
A symbol can't be repeated four times in a row. 90 is XC (100 − 10), not LXXXX, so 496 is CDXCVI.
Wrong: CCCCLXXXXVI
Why isn't 496 written as CCCCLXXXXVI?
No symbol can be repeated four times in a row, so CCCC and LXXXX are not used: 400 = CD, 90 = XC. Together they make CDXCVI.
