5. ## Re: [APP] Math Professional

Does it store variables (matrices, strings, numbers etc) with a name and within a folder hierarchy, so they can be pulled up later as needed?... or you have to type in your variable values each time?

Does it provide capability to save a program (combine mathematical operations in predefined manner), again with a name within a folder structure?... or you have to type them in each time?
