Basic Calculator

Calculator

Keyboard works too: digits, + - * / % . Enter for =, Backspace to delete, Esc to clear.

Notes

• Operator precedence applies: x and / are calculated before + and -, so 12 + 8 x 3 = 36.
• % turns the current number into a plain percentage: 50 % = 0.5. It does not do "percent of the previous number".
• Everything runs on your device; nothing is sent anywhere.
