| Place | Value | Numeral | Rule used |
|---|---|---|---|
| hundreds | 100 | C | one symbol |
| tens | 50 | L | the five symbol on its own |
| ones | 6 | VI | the five symbol plus one |
Check CLVI by reading it back
Reading CLVI from left to right and adding the pieces: C = 100, L = 50, VI = 6. Together that is 100 + 50 + 6 = 156, so CLVI and 156 match.
Mistakes to avoid with CLVI
- Never repeat a symbol more than three times in a row. When a fourth would be needed, the subtractive form takes over.
- Only I, X and C may be placed before a larger symbol to subtract, so CLVI never contains forms such as VX or LC.
- Read CLVI as one number, not letter by letter: add the values left to right, except where a smaller symbol sits before a larger one.
