How MMMDXCI is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 3000 | MMM |
| Hundreds | 500 | D |
| Tens | 90 | X (subtracted)C |
| Units | 1 | I |
| Total | 3591 | MMMDXCI |
MMMDXCI is written one place at a time, from the largest to the smallest: MMM (3000) + D (500) + XC (90) + I (1) = 3591.
XC is the only subtraction: the X before the C takes away 10, so XC = 90.
Common mistakes
Wrong: MMMDLXXXXI
Why isn't 3591 written as MMMDLXXXXI?
A symbol can't be repeated four times in a row. 90 is XC (100 − 10), not LXXXX, so 3591 is MMMDXCI.
