How CXCIII is formed
| Place | Value | Symbols |
|---|---|---|
| Hundreds | 100 | C |
| Tens | 90 | X (subtracted)C |
| Units | 3 | III |
| Total | 193 | CXCIII |
CXCIII is written one place at a time, from the largest to the smallest: C (100) + XC (90) + III (3) = 193.
XC is the only subtraction: the X before the C takes away 10, so XC = 90.
Common mistakes
Wrong: CLXXXXIII
Why isn't 193 written as CLXXXXIII?
A symbol can't be repeated four times in a row. 90 is XC (100 − 10), not LXXXX, so 193 is CXCIII.
