How CXLVII is formed
| Place | Value | Symbols |
|---|---|---|
| Hundreds | 100 | C |
| Tens | 40 | X (subtracted)L |
| Units | 7 | VII |
| Total | 147 | CXLVII |
CXLVII is written one place at a time, from the largest to the smallest: C (100) + XL (40) + VII (7) = 147.
XL is the only subtraction: the X before the L takes away 10, so XL = 40.
Common mistakes
Wrong: CXXXXVII
Why isn't 147 written as CXXXXVII?
A symbol can't be repeated four times in a row. 40 is XL (50 − 10), not XXXX, so 147 is CXLVII.
