How MCCXLII is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 1000 | M |
| Hundreds | 200 | CC |
| Tens | 40 | X (subtracted)L |
| Units | 2 | II |
| Total | 1242 | MCCXLII |
MCCXLII is written one place at a time, from the largest to the smallest: M (1000) + CC (200) + XL (40) + II (2) = 1242.
XL is the only subtraction: the X before the L takes away 10, so XL = 40.
Common mistakes
Wrong: MCCXXXXII
Why isn't 1242 written as MCCXXXXII?
A symbol can't be repeated four times in a row. 40 is XL (50 − 10), not XXXX, so 1242 is MCCXLII.
