How MMCLIX is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 2000 | MM |
| Hundreds | 100 | C |
| Tens | 50 | L |
| Units | 9 | I (subtracted)X |
| Total | 2159 | MMCLIX |
MMCLIX is written one place at a time, from the largest to the smallest: MM (2000) + C (100) + L (50) + IX (9) = 2159.
IX is the only subtraction: the I before the X takes away 1, so IX = 9.
Common mistakes
Wrong: MMCLVIIII
Why isn't 2159 written as MMCLVIIII?
A symbol can't be repeated four times in a row. 9 is IX (10 − 1), not VIIII, so 2159 is MMCLIX.
