How CMLXXXVIII is formed
| Place | Value | Symbols |
|---|---|---|
| Hundreds | 900 | C (subtracted)M |
| Tens | 80 | LXXX |
| Units | 8 | VIII |
| Total | 988 | CMLXXXVIII |
CMLXXXVIII is written one place at a time, from the largest to the smallest: CM (900) + LXXX (80) + VIII (8) = 988.
CM is the only subtraction: the C before the M takes away 100, so CM = 900.
Common mistakes
Wrong: DCCCCLXXXVIII
Why isn't 988 written as DCCCCLXXXVIII?
A symbol can't be repeated four times in a row. 900 is CM (1000 − 100), not DCCCC, so 988 is CMLXXXVIII.
Wrong: CMXXCVIII
Why isn't 988 written as CMXXCVIII?
Only one smaller symbol can stand before a larger one, so XXC doesn't work. 80 is LXXX (50 + 30), so 988 is CMLXXXVIII.
Wrong: CMLXXXIIX
Why isn't 988 written as CMLXXXIIX?
Only one smaller symbol can stand before a larger one, so IIX doesn't work. 8 is VIII (5 + 3), so 988 is CMLXXXVIII.
