How MMMDCCCXLVII is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 3000 | MMM |
| Hundreds | 800 | DCCC |
| Tens | 40 | X (subtracted)L |
| Units | 7 | VII |
| Total | 3847 | MMMDCCCXLVII |
MMMDCCCXLVII is written one place at a time, from the largest to the smallest: MMM (3000) + DCCC (800) + XL (40) + VII (7) = 3847.
XL is the only subtraction: the X before the L takes away 10, so XL = 40.
Common mistakes
Wrong: MMMDCCCXXXXVII
Why isn't 3847 written as MMMDCCCXXXXVII?
A symbol can't be repeated four times in a row. 40 is XL (50 − 10), not XXXX, so 3847 is MMMDCCCXLVII.
Wrong: MMMCCMXLVII
Why isn't 3847 written as MMMCCMXLVII?
Only one smaller symbol can stand before a larger one, so CCM doesn't work. 800 is DCCC (500 + 300), so 3847 is MMMDCCCXLVII.
