How MMDCXLIX is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 2000 | MM |
| Hundreds | 600 | DC |
| Tens | 40 | X (subtracted)L |
| Units | 9 | I (subtracted)X |
| Total | 2649 | MMDCXLIX |
MMDCXLIX is written one place at a time, from the largest to the smallest: MM (2000) + DC (600) + XL (40) + IX (9) = 2649.
XL and IX are subtractive pairs: in each one the smaller symbol comes first and is taken away.
Common mistakes
Wrong: MMDCIL
Why isn't 2649 written as MMDCIL?
I can only be subtracted from V and X, so IL (50 − 1) is not a valid pair. Write each place separately: MM (2000) + DC (600) + XL (40) + IX (9) = MMDCXLIX.
Wrong: MMDCXXXXIX
Why isn't 2649 written as MMDCXXXXIX?
A symbol can't be repeated four times in a row. 40 is XL (50 − 10), not XXXX, so 2649 is MMDCXLIX.
Wrong: MMDCXLVIIII
Why isn't 2649 written as MMDCXLVIIII?
A symbol can't be repeated four times in a row. 9 is IX (10 − 1), not VIIII, so 2649 is MMDCXLIX.
