How to Use the Scientific Calculator

Enter mathematical expressions using the on-screen buttons or your keyboard. The calculator evaluates your expression in real-time as you type, showing both the expression and the computed result. Press the equals button or hit Enter to finalize a calculation and add it to your history.

  • Build expressions naturally — type something like sin(45) + log10(100) and see the result update live.
  • Toggle DEG / RAD — switch between degrees and radians for trigonometric functions using the toggle in the display area.
  • Use ANS — the ANS button inserts the result of your last calculation, making it easy to chain computations.
  • Memory functions — use M+, M-, MR, and MC to store, recall, and clear a value in memory.
  • History — your last 10 calculations appear below the calculator. Click any entry to load its result back into the expression.
