How MMMCXLII is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 3000 | MMM |
| Hundreds | 100 | C |
| Tens | 40 | X (subtracted)L |
| Units | 2 | II |
| Total | 3142 | MMMCXLII |
MMMCXLII is written one place at a time, from the largest to the smallest: MMM (3000) + C (100) + XL (40) + II (2) = 3142.
XL is the only subtraction: the X before the L takes away 10, so XL = 40.
Common mistakes
Wrong: MMMCXXXXII
Why isn't 3142 written as MMMCXXXXII?
A symbol can't be repeated four times in a row. 40 is XL (50 − 10), not XXXX, so 3142 is MMMCXLII.
