How CXL is formed
| Place | Value | Symbols |
|---|---|---|
| Hundreds | 100 | C |
| Tens | 40 | X (subtracted)L |
| Total | 140 | CXL |
CXL is written one place at a time, from the largest to the smallest: C (100) + XL (40) = 140.
XL is the only subtraction: the X before the L takes away 10, so XL = 40.
Common mistakes
Wrong: CXXXX
Why isn't 140 written as CXXXX?
A symbol can't be repeated four times in a row. 40 is XL (50 − 10), not XXXX, so 140 is CXL.
