How CMXLII is formed
| Place | Value | Symbols |
|---|---|---|
| Hundreds | 900 | C (subtracted)M |

CMXLII is written one place at a time, from the largest to the smallest: CM (900) + XL (40) + II (2) = 942.
CM and XL are subtractive pairs: in each one the smaller symbol comes first and is taken away.
Common mistakes
Wrong: DCCCCXLII
Why isn't 942 written as DCCCCXLII?
A symbol can't be repeated four times in a row. 900 is CM (1000 − 100), not DCCCC, so 942 is CMXLII.
Wrong: CMXXXXII
Why isn't 942 written as CMXXXXII?
A symbol can't be repeated four times in a row. 40 is XL (50 − 10), not XXXX, so 942 is CMXLII.
Wrong: DCCCCXXXXII
Why isn't 942 written as DCCCCXXXXII?
No symbol can be repeated four times in a row, so DCCCC and XXXX are not used: 900 = CM, 40 = XL. Together they make CMXLII.
