How MMCMXC is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 2000 | MM |
| Hundreds | 900 | C (subtracted)M |
| Tens | 90 | X (subtracted)C |
| Total | 2990 | MMCMXC |
MMCMXC is written one place at a time, from the largest to the smallest: MM (2000) + CM (900) + XC (90) = 2990.
CM and XC are subtractive pairs: in each one the smaller symbol comes first and is taken away.
Common mistakes
Wrong: MMXM
Why isn't 2990 written as MMXM?
X can only be subtracted from L and C, so XM (1000 − 10) is not a valid pair. Write each place separately: MM (2000) + CM (900) + XC (90) = MMCMXC.
Wrong: MMDCCCCXC
Why isn't 2990 written as MMDCCCCXC?
A symbol can't be repeated four times in a row. 900 is CM (1000 − 100), not DCCCC, so 2990 is MMCMXC.
Wrong: MMCMLXXXX
Why isn't 2990 written as MMCMLXXXX?
A symbol can't be repeated four times in a row. 90 is XC (100 − 10), not LXXXX, so 2990 is MMCMXC.
