How MMDCXLVII is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 2000 | MM |
| Hundreds | 600 | DC |
| Tens | 40 | X (subtracted)L |
| Units | 7 | VII |
| Total | 2647 | MMDCXLVII |
MMDCXLVII is written one place at a time, from the largest to the smallest: MM (2000) + DC (600) + XL (40) + VII (7) = 2647.
XL is the only subtraction: the X before the L takes away 10, so XL = 40.
Common mistakes
Wrong: MMDCXXXXVII
Why isn't 2647 written as MMDCXXXXVII?
A symbol can't be repeated four times in a row. 40 is XL (50 − 10), not XXXX, so 2647 is MMDCXLVII.
