How MMCDLXXXI is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 2000 | MM |
| Hundreds | 400 | C (subtracted)D |
| Tens | 80 | LXXX |
| Units | 1 | I |
| Total | 2481 | MMCDLXXXI |
MMCDLXXXI is written one place at a time, from the largest to the smallest: MM (2000) + CD (400) + LXXX (80) + I (1) = 2481.
CD is the only subtraction: the C before the D takes away 100, so CD = 400.
Common mistakes
Wrong: MMCCCCLXXXI
Why isn't 2481 written as MMCCCCLXXXI?
A symbol can't be repeated four times in a row. 400 is CD (500 − 100), not CCCC, so 2481 is MMCDLXXXI.
Wrong: MMCDXXCI
Why isn't 2481 written as MMCDXXCI?
Only one smaller symbol can stand before a larger one, so XXC doesn't work. 80 is LXXX (50 + 30), so 2481 is MMCDLXXXI.
