How MMMDCXC is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 3000 | MMM |
| Hundreds | 600 | DC |
| Tens | 90 | X (subtracted)C |
| Total | 3690 | MMMDCXC |
MMMDCXC is written one place at a time, from the largest to the smallest: MMM (3000) + DC (600) + XC (90) = 3690.
XC is the only subtraction: the X before the C takes away 10, so XC = 90.
Common mistakes
Wrong: MMMDCLXXXX
Why isn't 3690 written as MMMDCLXXXX?
A symbol can't be repeated four times in a row. 90 is XC (100 − 10), not LXXXX, so 3690 is MMMDCXC.
