Frequently asked
Does it handle negative fractions?
Yes — enter a negative numerator. The sign is preserved through every operation.
What if I divide by zero?
Division by 0/x or by a zero numerator returns no result. Enter non-zero values.
Can I use mixed numbers?
Convert mixed numbers to improper fractions first (e.g. 1 1/2 → 3/2). A mixed-number mode is on the roadmap.
