How MMMDCCCXLII is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 3000 | MMM |
| Hundreds | 800 | DCCC |
| Tens | 40 | X (subtracted)L |
| Units | 2 | II |
| Total | 3842 | MMMDCCCXLII |
MMMDCCCXLII is written one place at a time, from the largest to the smallest: MMM (3000) + DCCC (800) + XL (40) + II (2) = 3842.
XL is the only subtraction: the X before the L takes away 10, so XL = 40.
Common mistakes
Wrong: MMMDCCCXXXXII
Why isn't 3842 written as MMMDCCCXXXXII?
A symbol can't be repeated four times in a row. 40 is XL (50 − 10), not XXXX, so 3842 is MMMDCCCXLII.
Wrong: MMMCCMXLII
Why isn't 3842 written as MMMCCMXLII?
Only one smaller symbol can stand before a larger one, so CCM doesn't work. 800 is DCCC (500 + 300), so 3842 is MMMDCCCXLII.
