Frequently asked questions
- How is this different from the scientific calculator?
- This one keeps to the four basic operations for speed. If you need trigonometry, logarithms, powers, or parentheses, use the scientific calculator — this tool deliberately leaves those out to stay uncluttered.
- What happens if I divide by zero?
- Division by zero is undefined, so the calculator shows an error or infinity indicator rather than a normal number. That is expected — there is no valid numeric answer.
- Do I need an internet connection?
- Only to load the page the first time. After that it runs in your browser and keeps working offline; it never contacts a server to do the math.
