How MMCMXX is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 2000 | MM |
| Hundreds | 900 | C (subtracted)M |
| Tens | 20 | XX |
| Total | 2920 | MMCMXX |
MMCMXX is written one place at a time, from the largest to the smallest: MM (2000) + CM (900) + XX (20) = 2920.
CM is the only subtraction: the C before the M takes away 100, so CM = 900.
Common mistakes
Wrong: MMDCCCCXX
Why isn't 2920 written as MMDCCCCXX?
A symbol can't be repeated four times in a row. 900 is CM (1000 − 100), not DCCCC, so 2920 is MMCMXX.
