How DCXCIII is formed
| Place | Value | Symbols |
|---|---|---|
| Hundreds | 600 | DC |
| Tens | 90 | X (subtracted)C |
| Units | 3 | III |
| Total | 693 | DCXCIII |
DCXCIII is written one place at a time, from the largest to the smallest: DC (600) + XC (90) + III (3) = 693.
XC is the only subtraction: the X before the C takes away 10, so XC = 90.
Common mistakes
Wrong: DCLXXXXIII
Why isn't 693 written as DCLXXXXIII?
A symbol can't be repeated four times in a row. 90 is XC (100 − 10), not LXXXX, so 693 is DCXCIII.
