How CDXCII is formed
| Place | Value | Symbols |
|---|---|---|

CDXCII is written one place at a time, from the largest to the smallest: CD (400) + XC (90) + II (2) = 492.
CD and XC are subtractive pairs: in each one the smaller symbol comes first and is taken away.
Common mistakes
Wrong: CCCCXCII
Why isn't 492 written as CCCCXCII?
A symbol can't be repeated four times in a row. 400 is CD (500 − 100), not CCCC, so 492 is CDXCII.
Wrong: CDLXXXXII
Why isn't 492 written as CDLXXXXII?
A symbol can't be repeated four times in a row. 90 is XC (100 − 10), not LXXXX, so 492 is CDXCII.
Wrong: CCCCLXXXXII
Why isn't 492 written as CCCCLXXXXII?
No symbol can be repeated four times in a row, so CCCC and LXXXX are not used: 400 = CD, 90 = XC. Together they make CDXCII.
