Daily UI #004 - Calculator

My entry for #DailyUI 004. Calculator

I wanted to try to make a calculator for a smart watch. Given i have never acted ever with a smart watch before, i have no idea how feasible this idea is. Most likely the buttons are WAY to small to be pressed.

I went through a few designs with bigger buttons and contant switching between menus (numbers, operators, etc) but finally decided on the small buttons.
