Three Screens Calculator & Unit Converter

This is a new calculator with 3 inputs. They work like 3 calculators on one screen. This is the calculator in my dream and I am so happy that it comes to my life. So I want to share it. It takes some time to get used to the calculator. Please watch the movie to see how it works. The calculator will save your calculating time, pens and paper.
