An XCas question....

I needed to edit that post, due to the image I inserted. I used this only as an example. The broader point is that some results are almost as difficult to resolve as the underlying problem being solved. This is an area where improvement is needed.

I sense there is a difference of opinion between educators, and students or other users. One point of view is that the user needs to be able to manipulate any process result, and a counterpoint is that the user wants to just USE the process result.

As a student, I would rarely need a calculator for these kind of problems. The advantage it can offer, is to confirm results that students obtain. For other users, the idea is often to move from the calculator to finished project, efficiently.
