How CCXLV is formed
| Place | Value | Symbols |
|---|---|---|
| Hundreds | 200 | CC |
| Tens | 40 | X (subtracted)L |
| Units | 5 | V |
| Total | 245 | CCXLV |
CCXLV is written one place at a time, from the largest to the smallest: CC (200) + XL (40) + V (5) = 245.
XL is the only subtraction: the X before the L takes away 10, so XL = 40.
Common mistakes
Wrong: CCVL
Why isn't 245 written as CCVL?
V is never subtracted; only I, X and C can come before a larger symbol. Write each place separately: CC (200) + XL (40) + V (5) = CCXLV.
Wrong: CCXXXXV
Why isn't 245 written as CCXXXXV?
A symbol can't be repeated four times in a row. 40 is XL (50 − 10), not XXXX, so 245 is CCXLV.
