How CDL is formed
| Place | Value | Symbols |
|---|---|---|
| Hundreds | 400 | C (subtracted)D |
| Tens | 50 | L |
| Total | 450 | CDL |
CDL is written one place at a time, from the largest to the smallest: CD (400) + L (50) = 450.
CD is the only subtraction: the C before the D takes away 100, so CD = 400.
Common mistakes
Wrong: LD
Why isn't 450 written as LD?
L is never subtracted; only I, X and C can come before a larger symbol. Write each place separately: CD (400) + L (50) = CDL.
Wrong: CCCCL
Why isn't 450 written as CCCCL?
A symbol can't be repeated four times in a row. 400 is CD (500 − 100), not CCCC, so 450 is CDL.
