How to Use

  1. Click the calculator buttons or use your keyboard to input numbers and operations.
  2. Use scientific functions (sin, cos, tan, log, ln, sqrt) for advanced calculations.
  3. Memory functions (MC, MR, M+, M-) let you store and recall values.
  4. Press = or Enter to calculate the result.
  5. View your calculation history in the panel below.
  6. Click on any history item to reuse that calculation.
  7. Use AC (All Clear) or Escape key to reset the calculator.

Frequently Asked Questions

Can I use keyboard shortcuts?

Yes! Use number keys, operators (+, -, *, /), Enter for equals, Escape to clear all, and Backspace to delete the last character.

How do I switch between degrees and radians?

Click the DEG/RAD button to toggle between degree and radian mode for trigonometric calculations. The current mode is displayed above the calculator.

Is there a limit to calculation history?

The calculator stores your last 50 calculations. You can click on any history item to reuse it, or click "Clear" to empty the history.

How accurate are the calculations?

Calculations use JavaScript's floating-point arithmetic with standard precision. For most practical purposes, results are accurate to many decimal places.

Is my calculation history stored?

Calculation history is stored only in your browser session. It will be cleared when you close or refresh the page. No data is sent to our servers.
