How XLII is formed
| Place | Value | Symbols |
|---|---|---|
| Tens | 40 | X (subtracted)L |
| Units | 2 | II |
| Total | 42 | XLII |
XLII is written one place at a time, from the largest to the smallest: XL (40) + II (2) = 42.
XL is the only subtraction: the X before the L takes away 10, so XL = 40.
Common mistakes
Wrong: XXXXII
Why isn't 42 written as XXXXII?
A symbol can't be repeated four times in a row. 40 is XL (50 − 10), not XXXX, so 42 is XLII.
