How MMMCDLXXXVII is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 3000 | MMM |
| Hundreds | 400 | C (subtracted)D |
| Tens | 80 | LXXX |
| Units | 7 | VII |
| Total | 3487 | MMMCDLXXXVII |
MMMCDLXXXVII is written one place at a time, from the largest to the smallest: MMM (3000) + CD (400) + LXXX (80) + VII (7) = 3487.
CD is the only subtraction: the C before the D takes away 100, so CD = 400.
Common mistakes
Wrong: MMMCCCCLXXXVII
Why isn't 3487 written as MMMCCCCLXXXVII?
A symbol can't be repeated four times in a row. 400 is CD (500 − 100), not CCCC, so 3487 is MMMCDLXXXVII.
Wrong: MMMCDXXCVII
Why isn't 3487 written as MMMCDXXCVII?
Only one smaller symbol can stand before a larger one, so XXC doesn't work. 80 is LXXX (50 + 30), so 3487 is MMMCDLXXXVII.
