How MMDCCCXLVII is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 2000 | MM |
| Hundreds | 800 | DCCC |
| Tens | 40 | X (subtracted)L |
| Units | 7 | VII |
| Total | 2847 | MMDCCCXLVII |
MMDCCCXLVII is written one place at a time, from the largest to the smallest: MM (2000) + DCCC (800) + XL (40) + VII (7) = 2847.
XL is the only subtraction: the X before the L takes away 10, so XL = 40.
Common mistakes
Wrong: MMDCCCXXXXVII
Why isn't 2847 written as MMDCCCXXXXVII?
A symbol can't be repeated four times in a row. 40 is XL (50 − 10), not XXXX, so 2847 is MMDCCCXLVII.
Wrong: MMCCMXLVII
Why isn't 2847 written as MMCCMXLVII?
Only one smaller symbol can stand before a larger one, so CCM doesn't work. 800 is DCCC (500 + 300), so 2847 is MMDCCCXLVII.
