Simple Calculator

A clear, easy-to-use calculator with large buttons and a big display. Add, subtract, multiply, divide, and calculate percentages with confidence.

How It Works

Tap the number buttons to enter a value, choose an operation (add, subtract, multiply, divide), enter the second number, then press = to see the result. The display shows both the current expression and the answer.

Buttons

AC - Clears everything and starts fresh.
Backspace - Deletes the last digit you typed.
% - Converts the current number to a percentage (divides by 100). For example, typing 20 then % gives 0.2, so 500 + 20% = 600.
+ − × ÷ - Standard math operations.
= - Calculates and shows the final result.

Chaining Calculations

After pressing =, you can keep going. The result becomes the starting number for your next calculation. Just press an operator and continue.

Privacy

All calculations happen instantly in your browser. Nothing is sent to any server. No account or login needed.
