DailyUI Day 4: Calculator.

Today I happened to read this article about the ergonomic thinking behind numerical keypad. The topic is so fun and I am inspired to create this calculator interface.

The numbers, 4 common operators and result cta are close to the convenient touch of your right thumb if this is a mobile screen.

Let me know what you think!
