Calculate+4 vs Simple Calculator Multi

I made the concept that, want to use a calculator on a tablet and also want to use a calculator with a simple design. The buttons are large and easy to touch, and have a simple design. In calculator + 4 we put four calculators on one screen when we turned horizontally. I think that it is useful in various places if you have to do simultaneous calculation.
