How MMCDXLIX is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 2000 | MM |
| Hundreds | 400 | C (subtracted)D |
| Tens | 40 | X (subtracted)L |
| Units | 9 | I (subtracted)X |
| Total | 2449 | MMCDXLIX |
MMCDXLIX is written one place at a time, from the largest to the smallest: MM (2000) + CD (400) + XL (40) + IX (9) = 2449.
CD, XL, and IX are subtractive pairs: in each one the smaller symbol comes first and is taken away.
Common mistakes
Wrong: MMCDIL
Why isn't 2449 written as MMCDIL?
I can only be subtracted from V and X, so IL (50 − 1) is not a valid pair. Write each place separately: MM (2000) + CD (400) + XL (40) + IX (9) = MMCDXLIX.
Wrong: MMCCCCXLIX
Why isn't 2449 written as MMCCCCXLIX?
A symbol can't be repeated four times in a row. 400 is CD (500 − 100), not CCCC, so 2449 is MMCDXLIX.
Wrong: MMCDXXXXIX
Why isn't 2449 written as MMCDXXXXIX?
A symbol can't be repeated four times in a row. 40 is XL (50 − 10), not XXXX, so 2449 is MMCDXLIX.
