Every time you hit the C button to clear, your equation is saved to the history screen, as in 7.png. You can tap on one of those equations and bring it back up on the main screen, to edit and calculate again.
That means that I can enter the equations for Hc, t and Z and use it just like the fx-82AU. The latter will still win hands down because of its far superior battery performance compared to a smartphone.
