How MCDXLIX is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 1000 | M |
| Hundreds | 400 | C (subtracted)D |
| Tens | 40 | X (subtracted)L |
| Units | 9 | I (subtracted)X |
| Total | 1449 | MCDXLIX |
MCDXLIX is written one place at a time, from the largest to the smallest: M (1000) + CD (400) + XL (40) + IX (9) = 1449.
CD, XL, and IX are subtractive pairs: in each one the smaller symbol comes first and is taken away.
Common mistakes
Wrong: MCDIL
Why isn't 1449 written as MCDIL?
I can only be subtracted from V and X, so IL (50 − 1) is not a valid pair. Write each place separately: M (1000) + CD (400) + XL (40) + IX (9) = MCDXLIX.
Wrong: MCCCCXLIX
Why isn't 1449 written as MCCCCXLIX?
A symbol can't be repeated four times in a row. 400 is CD (500 − 100), not CCCC, so 1449 is MCDXLIX.
Wrong: MCDXXXXIX
Why isn't 1449 written as MCDXXXXIX?
A symbol can't be repeated four times in a row. 40 is XL (50 − 10), not XXXX, so 1449 is MCDXLIX.
