How MMCDLVI is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 2000 | MM |
| Hundreds | 400 | C (subtracted)D |
| Tens | 50 | L |
| Units | 6 | VI |
| Total | 2456 | MMCDLVI |
MMCDLVI is written one place at a time, from the largest to the smallest: MM (2000) + CD (400) + L (50) + VI (6) = 2456.
CD is the only subtraction: the C before the D takes away 100, so CD = 400.
Common mistakes
Wrong: MMCCCCLVI
Why isn't 2456 written as MMCCCCLVI?
A symbol can't be repeated four times in a row. 400 is CD (500 − 100), not CCCC, so 2456 is MMCDLVI.
