How the Basic Calculator Works
- Enter your first number using the digit buttons.
- Press an operator — +, −, ×, or ÷.
- Enter your second number, then press = to see the result.
- Press AC to clear everything, or C to clear the current entry.
- Use % to work out a percentage — after an operator it applies to the first number (200 × 15% = 30); on its own it divides by 100. Use +/− to switch a number between positive and negative.

Frequently Asked Questions
What does AC vs C do?
AC (All Clear) resets the calculator completely. C appears mid-entry and clears only the current number, keeping your operator and previous value so you can re-enter it.
How does the % button work?
Press % to divide the current number by 100. If you have already entered an operator and a first number, % applies relative to that — for example 200 × 15% gives 30.
Can I chain multiple operations?
Yes. Enter a number, press an operator, enter the next number, then press another operator — the calculator evaluates left-to-right as you go.
