How CDXCV is formed
| Place | Value | Symbols |
|---|---|---|
| Hundreds | 400 | C (subtracted)D |
| Tens | 90 | X (subtracted)C |
| Units | 5 | V |
| Total | 495 | CDXCV |
CDXCV is written one place at a time, from the largest to the smallest: CD (400) + XC (90) + V (5) = 495.
CD and XC are subtractive pairs: in each one the smaller symbol comes first and is taken away.
Common mistakes
Wrong: VD
Why isn't 495 written as VD?
V is never subtracted; only I, X and C can come before a larger symbol. Write each place separately: CD (400) + XC (90) + V (5) = CDXCV.
Wrong: CDVC
Why isn't 495 written as CDVC?
V is never subtracted; only I, X and C can come before a larger symbol. Write each place separately: CD (400) + XC (90) + V (5) = CDXCV.
Wrong: CCCCXCV
Why isn't 495 written as CCCCXCV?
A symbol can't be repeated four times in a row. 400 is CD (500 − 100), not CCCC, so 495 is CDXCV.
