The number XIIV is impossible in Roman numerals, as it features two numbers less than V to the direct left of V. The Roman numeral which represents the number 5 - (1 + 1) = 3 less than 10 (X) = 13, is XIII.
The Roman numerals for 1-15 are: 1 - I 2 - II 3 - III 4 - IV 5 - V 6 - VI 7 - VII 8 - VIII 9 - IX 10 - X 11 - XI 12 - XII 13 - XIII 14 - XIV 15 - XV
