How MMCDLXXXVII is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 2000 | MM |
| Hundreds | 400 | C (subtracted)D |
| Tens | 80 | LXXX |
| Units | 7 | VII |
| Total | 2487 | MMCDLXXXVII |
MMCDLXXXVII is written one place at a time, from the largest to the smallest: MM (2000) + CD (400) + LXXX (80) + VII (7) = 2487.
CD is the only subtraction: the C before the D takes away 100, so CD = 400.
Common mistakes
Wrong: MMCCCCLXXXVII
Why isn't 2487 written as MMCCCCLXXXVII?
A symbol can't be repeated four times in a row. 400 is CD (500 − 100), not CCCC, so 2487 is MMCDLXXXVII.
Wrong: MMCDXXCVII
Why isn't 2487 written as MMCDXXCVII?
Only one smaller symbol can stand before a larger one, so XXC doesn't work. 80 is LXXX (50 + 30), so 2487 is MMCDLXXXVII.
