Design Hint: Design a calculator. Standard, scientific, or specialty calculator for something such as a mortgage? Is it for a phone, a tablet, a web app?
Solution: I decided to create a desktop app, very simple and minimal for simple calculations. What’s different about my approach is the fact that you can drag the main screen with your result and place it to the side. How many times have you forgotten the previous number when you were doing multiple-step calculations? Well, now you can have all the steps next to the one you’re working on so you don’t miss anything. If you need to use the calculator again in one of the screens you dragged from the main app, you just click the arrow and open the whole screen again.
