| Symbol | Value |
|---|---|
| I | 1 |
| V | 5 |
| X | 10 |
| L | 50 |
| C | 100 |
| D | 500 |
| M | 1000 |
Generally, Roman numerals are written in descending order from left to right, and are added sequentially,
for example MMVI (2006) is interpreted as 1000 + 1000 + 5 + 1.
Certain combinations employ a subtractive principle, which specifies that where a symbol of smaller value
precedes a symbol of larger value, the smaller value is subtracted from the larger value, and the result is
added to the total. For example, in MCMXLIV (1944), the symbols C, X and I each precede a symbol of
higher value, and the result is interpreted as 1000 plus (1000 minus 100) plus (50 minus 10) plus (5
minus 1).
