EXAMPLE CALCULATIONS
X + V = XV
10 + 5 = 15
XX − VII = XIII
20 - 7 = 13
VI × IV = XXIV
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.
