None of the view choices are showing up on my screen

I am trying to follow online tutorials for changing the background of a photo in Elements (I have 14) - to a plain background, for which I believe expert mode is required. But my question is about something more basic. Right now, the view choices such as the eraser tool, which the tutorials are saying to use, are not coming up on the left of my screen at all. How do I bring them back?
