How do I pull up a screen so that I can try to work out the solution on the openstudy site? I have tried to cut and paste from an app on my iPad, but that's not been successful.  Anybody out there conversant with Prof. Halmos's classic "Naive Set Theory"?

I did not phrase the first question very well. At times, I have opened a screen to demonstrate a solution. Below the screen were several utilities: a graphing utility, a blank page to work on and deposit, and a screen with common symbols such as integral sign, functional notation, pi,  e, etc. the screen was non-responsive to my attempts at input. I reiterate the question about Prof. Halmos.
