How MDCLIX is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 1000 | M |
| Hundreds | 600 | DC |
| Tens | 50 | L |
| Units | 9 | I (subtracted)X |
| Total | 1659 | MDCLIX |
MDCLIX is written one place at a time, from the largest to the smallest: M (1000) + DC (600) + L (50) + IX (9) = 1659.
IX is the only subtraction: the I before the X takes away 1, so IX = 9.
Common mistakes
Wrong: MDCLVIIII
Why isn't 1659 written as MDCLVIIII?
A symbol can't be repeated four times in a row. 9 is IX (10 − 1), not VIIII, so 1659 is MDCLIX.
