Complete guide: Online Calculator
Updated:
This online calculator handles everyday operations: addition, subtraction, multiplication and division, with support for decimals, parentheses and percentages. It works the same on mobile and desktop, with no sign-up or downloads.
It respects the order of operations: parentheses first, then multiplication and division, and finally addition and subtraction. So 2 + 3 × 4 equals 14, not 20. Use parentheses when you want to force a different order.
The % button converts a number to its percent value: 50% equals 0.5. You can copy the result with one click to paste it wherever you need.
How it works
- 1Type the operation with the on-screen keypad.
- 2Use parentheses to group and % for percentages.
- 3Press = to see the result and copy it with one click.
