A few good questions

Before you dive in.

Can I move or back up my work?

Yes. Export your workspace, history, settings, variables, and graph definitions as JSON. Notes can also be exported as Markdown or plain text. File imports are previewed before they are applied.

Does it solve equations symbolically?

CalciteQuickSolve is a scientific calculator and graphing tool. It can show a numerical evaluation trace for supported calculations; it is not a symbolic algebra solver.
