How MDCCCXIX is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 1000 | M |
| Hundreds | 800 | DCCC |
| Tens | 10 | X |
| Units | 9 | I (subtracted)X |
| Total | 1819 | MDCCCXIX |
MDCCCXIX is written one place at a time, from the largest to the smallest: M (1000) + DCCC (800) + X (10) + IX (9) = 1819.
IX is the only subtraction: the I before the X takes away 1, so IX = 9.
Common mistakes
Wrong: MDCCCXVIIII
Why isn't 1819 written as MDCCCXVIIII?
A symbol can't be repeated four times in a row. 9 is IX (10 − 1), not VIIII, so 1819 is MDCCCXIX.
Wrong: MCCMXIX
Why isn't 1819 written as MCCMXIX?
Only one smaller symbol can stand before a larger one, so CCM doesn't work. 800 is DCCC (500 + 300), so 1819 is MDCCCXIX.
