How MMMDCCCXCVII is formed
| Place | Value | Symbols |
|---|---|---|
| Thousands | 3000 | MMM |
| Hundreds | 800 | DCCC |
| Tens | 90 | X (subtracted)C |
| Units | 7 | VII |
| Total | 3897 | MMMDCCCXCVII |
MMMDCCCXCVII is written one place at a time, from the largest to the smallest: MMM (3000) + DCCC (800) + XC (90) + VII (7) = 3897.
XC is the only subtraction: the X before the C takes away 10, so XC = 90.
Common mistakes
Wrong: MMMDCCCLXXXXVII
Why isn't 3897 written as MMMDCCCLXXXXVII?
A symbol can't be repeated four times in a row. 90 is XC (100 − 10), not LXXXX, so 3897 is MMMDCCCXCVII.
Wrong: MMMCCMXCVII
Why isn't 3897 written as MMMCCMXCVII?
Only one smaller symbol can stand before a larger one, so CCM doesn't work. 800 is DCCC (500 + 300), so 3897 is MMMDCCCXCVII.
