How MMDXL is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 2000 | MM |
| Hundreds | 500 | D |
| Tens | 40 | X (subtracted)L |
| Total | 2540 | MMDXL |
MMDXL is written one place at a time, from the largest to the smallest: MM (2000) + D (500) + XL (40) = 2540.
XL is the only subtraction: the X before the L takes away 10, so XL = 40.
Common mistakes
Wrong: MMDXXXX
Why isn't 2540 written as MMDXXXX?
A symbol can't be repeated four times in a row. 40 is XL (50 − 10), not XXXX, so 2540 is MMDXL.
