Adding and subtracting fractions requires a common denominator, achieved by cross-multiplying: a/b + c/d = (a×d + c×b) / (b×d). Multiplying fractions is simpler: multiply numerators together and denominators together. Dividing by a fraction is the same as multiplying by its reciprocal.
After calculating the result, this tool automatically simplifies the fraction by dividing both numerator and denominator by their greatest common divisor, so results like 4/8 are shown as the simplified 1/2.
Yes, this calculator supports negative numerators and denominators for all four operations.
Simplifying to lowest terms is standard mathematical practice and makes the result easier to read and use in further calculations.
