If an editing operation doesn't produce the results you intended, you can easily undo it in MoboMath. If you want to restore an operation after undoing it, you can also redo it.
To undo an editing operation:
Use one of these options.
Tap the Undo toolbar button or choose Undo from the Edit menu.
Use an undo gesture. To write the gesture, draw a line straight up and then straight down again, being careful not to lift your stylus between the up and down portions of the stroke.
In addition to its other uses, Undo is a convenient way to remove the last stroke or strokes.
To restore the results of an editing operation:
Use one of these options.
Tap the Redo toolbar button or choose Redo from the Edit menu.
Use a redo gesture. To write the gesture, draw a line straight down and then straight up again, being careful not to lift your stylus between the down and up portions of the stroke.
