They also serve as separate calculators that can interact with each other. For example, if you store an answer within one calculator, you can swipe across the color bar to recall and use it in another calculator. Whenever you have an equation with variables that can be plotted a “Touch to Plot” button will appear, allowing you to quickly turn it into a graph. The app is loaded with other great features, and thankfully in-depth tutorials are available to help you take full advantage of all of them.
