Rule III  :  The numeral V, L and D are never repeated.

            Rule IV  :  A Roman numeral of smaller value can be placed before another

                            of greater value only once. That is why it is wrong to write IIX, IIIX
                            or IIIC.





                              In the Roman numeral system, I, X

                              and C numerals can be repeated a
                                 maximum of three times only.
