EXAMPLE CALCULATIONS

X + V = XV

10 + 5 = 15

XX VII = XIII

20 - 7 = 13

6 × 4 = 24

L ÷ X = V

50 ÷ 10 = 5

ROMAN MATH RULES

LIMITATIONS

  • • No zero or negative numbers
  • • Division results are rounded down
  • • Results must be between 1-3999
  • • Only whole number results

HISTORICAL NOTE

Romans used an abacus for calculations, then converted results to Roman numerals. This calculator simulates that process digitally.
