How MMMCXLVII is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 3000 | MMM |
| Hundreds | 100 | C |
| Tens | 40 | X (subtracted)L |
| Units | 7 | VII |
| Total | 3147 | MMMCXLVII |
MMMCXLVII is written one place at a time, from the largest to the smallest: MMM (3000) + C (100) + XL (40) + VII (7) = 3147.
XL is the only subtraction: the X before the L takes away 10, so XL = 40.
Common mistakes
Wrong: MMMCXXXXVII
Why isn't 3147 written as MMMCXXXXVII?
A symbol can't be repeated four times in a row. 40 is XL (50 − 10), not XXXX, so 3147 is MMMCXLVII.
