Roman numbers like I (1), V (5), X(10), L (50), and C (100) act as bases for writing other numbers as other numbers are written by the combination of these Roman numbers.

For example : II (2), III (3),  IV (4), VIII (8),  IX (9), XII (12), XVIII (18), XL (40), LX (60), XCIX (99), etc.

Rules to write Roman numbers :

  1. Any symbol can be repeated maximum for 3 times like III (3), XXX (30), CC (200) or CCC (300).
  2. The letters D, L, and V are among a select few symbols in the Roman number system that are never repeated.
  3. When the symbol of lower value comes before the higher value symbol, it will be subtracted. For example IX = X – I = 9
