Frequently asked questions
Do the math calculators show their working?
Yes. Each result comes with a 'How it's calculated' panel showing the formula with your numbers substituted, step by step.
Can I use them for homework?
They are a good way to check answers and see the method. Show the steps in your own work rather than copying the result.
Do you round the answers?
Only the displayed value, usually to two decimals or the precision your inputs imply. The exact value is available in the steps panel.
