Basic Calculator: Simple Math

Basic Calculator is a simple, fast calculator for everyday sums. Tap the numbers and operations as you would on a pocket calculator, and the result appears on the display.

What you get
• Add, subtract, multiply and divide with a decimal point
• Percent (%) and plus/minus (±) keys to change the sign of the number on the display
• AC clears everything, and the back key removes the last digit
• Multiplication and division run before addition and subtraction, so 2 + 3 × 4 gives 14
• Large, easy-to-tap keys on the screen

Where it helps
• Quick sums at the shop, in class or at work
• Checking a bill, a tip or a discount in a few taps
• Working out a quick total without opening a spreadsheet
• Keeping a calculator handy on the phone, in light or dark theme

Made for daily use

• 28 languages, with right-to-left layout where it belongs
