Questions from the bench

Why is showing the working important?
Each result explains what happened, so you can verify the maths, understand the method and use it again. More useful than a bare number.
Do I need to create an account to use the calculators?
No. Calculator Cosmos does not require accounts and you can start calculating immediately.
Is my data private when using these calculators?
Yes. Inputs stay in your browser and never leave your device because the maths runs locally.
What should I include when reporting an issue?
Send the calculator URL, the values you entered if you are reporting a calculation issue, and what you expected to see.
