How MMDCXLVI is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 2000 | MM |
| Hundreds | 600 | DC |
| Tens | 40 | X (subtracted)L |
| Units | 6 | VI |
| Total | 2646 | MMDCXLVI |
MMDCXLVI is written one place at a time, from the largest to the smallest: MM (2000) + DC (600) + XL (40) + VI (6) = 2646.
XL is the only subtraction: the X before the L takes away 10, so XL = 40.
Common mistakes
Wrong: MMDCXXXXVI
Why isn't 2646 written as MMDCXXXXVI?
A symbol can't be repeated four times in a row. 40 is XL (50 − 10), not XXXX, so 2646 is MMDCXLVI.
