How MMCMXXVIII is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 2000 | MM |
| Hundreds | 900 | C (subtracted)M |
| Tens | 20 | XX |
| Units | 8 | VIII |
| Total | 2928 | MMCMXXVIII |
MMCMXXVIII is written one place at a time, from the largest to the smallest: MM (2000) + CM (900) + XX (20) + VIII (8) = 2928.
CM is the only subtraction: the C before the M takes away 100, so CM = 900.
Common mistakes
Wrong: MMDCCCCXXVIII
Why isn't 2928 written as MMDCCCCXXVIII?
A symbol can't be repeated four times in a row. 900 is CM (1000 − 100), not DCCCC, so 2928 is MMCMXXVIII.
Wrong: MMCMXXIIX
Why isn't 2928 written as MMCMXXIIX?
Only one smaller symbol can stand before a larger one, so IIX doesn't work. 8 is VIII (5 + 3), so 2928 is MMCMXXVIII.
