Place to learn

[MathmagicianTheMatthew]

Another issue is that I believe that there should be a place to learn firstly and then get these questions.

This tool is meant for revision, so the place to learn is not needed. What would you suggest a place to lean should have?

I believe there should be a page that lists all the different functions as well as giving examples of how to do it. This should be included because if someone forgets how to do a problem or encounters one they don't know how to do they can figure it out.
