How MMDCCCXLII is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 2000 | MM |
| Hundreds | 800 | DCCC |
| Tens | 40 | X (subtracted)L |
| Units | 2 | II |
| Total | 2842 | MMDCCCXLII |
MMDCCCXLII is written one place at a time, from the largest to the smallest: MM (2000) + DCCC (800) + XL (40) + II (2) = 2842.
XL is the only subtraction: the X before the L takes away 10, so XL = 40.
Common mistakes
Wrong: MMDCCCXXXXII
Why isn't 2842 written as MMDCCCXXXXII?
A symbol can't be repeated four times in a row. 40 is XL (50 − 10), not XXXX, so 2842 is MMDCCCXLII.
Wrong: MMCCMXLII
Why isn't 2842 written as MMCCMXLII?
Only one smaller symbol can stand before a larger one, so CCM doesn't work. 800 is DCCC (500 + 300), so 2842 is MMDCCCXLII.
