Q
5 Rules
A
- when repeated, add them together.
ex: III = I+I+I→3 - when a SMALLER roman # is written to the RIGHT of a larger #, ADD
ex: VI= V + I → 6 - when a SMALLER roman # is written to the LEFT of a larger #, SUBTRACT
ex: IX = X - I → 9 - Do not use more than 3 of the same Roman # in a sequence.
ex: IIII= 4 [wrong] , IV → 4 - when rule 2 + 3 are in conflict, use rule 3
ex: XIX= 21 [wrong] , XIX= 19
