- The letters are deducted when a smaller letter comes before a larger letter. For example: IV, I < V xss=removed xss=removed>
- When a letter is repeated multiple times, they get added. For example: MMM = M + M + M = 1000 + 1000 + 1000 = 3000
- You can't use the same letter more than three times in a row. V, L, and D cannot be repeated, they appear only once.
