How it works

To add or subtract, the calculator cross-multiplies so both fractions share the denominator bdbd, then combines the numerators. Multiplying is straight across; dividing flips the second fraction and multiplies.

The result is simplified by dividing top and bottom by their highest common factor, then shown as a mixed number and a decimal.
