How MDCCXLIX is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 1000 | M |
| Hundreds | 700 | DCC |
| Tens | 40 | X (subtracted)L |
| Units | 9 | I (subtracted)X |
| Total | 1749 | MDCCXLIX |
MDCCXLIX is written one place at a time, from the largest to the smallest: M (1000) + DCC (700) + XL (40) + IX (9) = 1749.
XL and IX are subtractive pairs: in each one the smaller symbol comes first and is taken away.
Common mistakes
Wrong: MDCCIL
Why isn't 1749 written as MDCCIL?
I can only be subtracted from V and X, so IL (50 − 1) is not a valid pair. Write each place separately: M (1000) + DCC (700) + XL (40) + IX (9) = MDCCXLIX.
Wrong: MDCCXXXXIX
Why isn't 1749 written as MDCCXXXXIX?
A symbol can't be repeated four times in a row. 40 is XL (50 − 10), not XXXX, so 1749 is MDCCXLIX.
Wrong: MDCCXLVIIII
Why isn't 1749 written as MDCCXLVIIII?
A symbol can't be repeated four times in a row. 9 is IX (10 − 1), not VIIII, so 1749 is MDCCXLIX.
