How DCCXLVII is formed
| Place | Value | Symbols |
|---|---|---|
| Hundreds | 700 | DCC |
| Tens | 40 | X (subtracted)L |
| Units | 7 | VII |
| Total | 747 | DCCXLVII |
DCCXLVII is written one place at a time, from the largest to the smallest: DCC (700) + XL (40) + VII (7) = 747.
XL is the only subtraction: the X before the L takes away 10, so XL = 40.
Common mistakes
Wrong: DCCXXXXVII
Why isn't 747 written as DCCXXXXVII?
A symbol can't be repeated four times in a row. 40 is XL (50 − 10), not XXXX, so 747 is DCCXLVII.
