How CCCXLII is formed
| Place | Value | Symbols |
|---|---|---|
| Hundreds | 300 | CCC |
| Tens | 40 | X (subtracted)L |
| Units | 2 | II |
| Total | 342 | CCCXLII |
CCCXLII is written one place at a time, from the largest to the smallest: CCC (300) + XL (40) + II (2) = 342.
XL is the only subtraction: the X before the L takes away 10, so XL = 40.
Common mistakes
Wrong: CCCXXXXII
Why isn't 342 written as CCCXXXXII?
A symbol can't be repeated four times in a row. 40 is XL (50 − 10), not XXXX, so 342 is CCCXLII.
