How MCCXCI is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 1000 | M |
| Hundreds | 200 | CC |
| Tens | 90 | X (subtracted)C |
| Units | 1 | I |
| Total | 1291 | MCCXCI |
MCCXCI is written one place at a time, from the largest to the smallest: M (1000) + CC (200) + XC (90) + I (1) = 1291.
XC is the only subtraction: the X before the C takes away 10, so XC = 90.
Common mistakes
Wrong: MCCLXXXXI
Why isn't 1291 written as MCCLXXXXI?
A symbol can't be repeated four times in a row. 90 is XC (100 − 10), not LXXXX, so 1291 is MCCXCI.
