Start Calculating →How to Use the Basic Calculator
Tap the keys or type on your keyboard. The calculator follows the standard order of operations, so multiplication and division are done before addition and subtraction, and anything in brackets is worked out first. For example, 2 + 3 × 4 equals 14, while (2 + 3) × 4 equals 20.
The percent key
Place % after a number to turn it into a percentage. 200 × 15% gives 30, because 15% is treated as 0.15. Place % between two numbers and it returns the remainder instead, so 17 % 5 gives 2. For percentage increase, decrease and discount problems, the dedicated
Percentage Calculator is easier.Memory keys
- M+ adds the number on the display to memory.

Keyboard shortcuts
Type digits and the symbols + - * / % ( ) and the decimal point. Press Enter to calculate, Backspace to delete the last character and Escape to clear the display. The Copy button copies the current result, and the history panel keeps your recent calculations.
Accurate decimals
Computers store decimals in binary, which can produce tiny rounding noise such as 0.30000000000000004. This calculator rounds the result to 12 decimal places so everyday sums like 0.1 + 0.2 show 0.3. Everything is calculated in your browser and nothing you type is sent to a server.
