A clean online calculator with an on-screen keypad. Add, subtract, multiply and divide — with chained operations, decimals, percent and sign change. Works with your keyboard too.
Tap the keypad or use your keyboard (0-9, + − × ÷, Enter, Esc, %).
A basic calculator performs the four core arithmetic operations: addition, subtraction, multiplication and division. This one also handles decimals, percent, sign change (±) and clearing the display, with an on-screen keypad you tap or click.
Press a number, an operator, another number, then a new operator and the calculator works out the running total before continuing. For example, 7 + 8 shows 15, and pressing ÷ 3 then = gives 5.
C clears everything and resets the display to 0. The ± button flips the sign of the number currently on screen, turning a positive number negative and a negative number positive.
