Frequently Asked Questions

Everything you need to know about this calculator.

Yes! This calculator is completely free with no usage limits, no registration and no hidden charges. Use it as many times as you want.
Absolutely. Number keys (top row and numeric keypad), +, −, * , / , Enter for result, Backspace to delete, and Esc to clear — all are supported. It works on every laptop and PC, regardless of keyboard layout or Num Lock status.
M+ adds the current number to memory, M− subtracts it, MR recalls the stored value to the screen, and MC clears the memory. A small "M" badge appears above the display when something is stored.
No. All calculations happen locally in your browser using JavaScript. Nothing is sent to any server, so your data stays 100% private. History clears automatically when you refresh the page.
Mathematically, division by zero is undefined — no number can be divided by zero. That's why the calculator shows "Error" instead of a result. Press Esc or C to start a new calculation.
For addition and subtraction (e.g., 200 + 10%), the percentage is calculated relative to the first number — so you get 220. On its own, % simply converts the current number to its decimal form (50% becomes 0.5).
