AnCalculator 1.1.0

The application to compute numbers with simple actions (addition, subtraction, multiplication, division) and functions inherented in a normal calculator. For instance:
Slot for memory keeping that keeps a number even if the app is closed;
Numbers can be erased from the end using button "backspace" (left-side arrow);
A user can change modularity (positive/negative numbers);
You can find percentage, square root and raise power for numbers.
All buttons have animation for enjoyable using. On a scoreboard (table) you can see the first and the second numbers and an action that we chose on the calculator.
The calculator is created for mobile devices on Android platform with not too big screen for the vertical orientation.
