But the idea of the explorations is: either when I know the shortcut or solutions, or when I do not know them, can I let the calculator solve most of the problem?

In particular that problem raised the problem of "hidden digits by the real representation" that then was solved first with a homemade program (and proper flags), then with the knowledge of Joe Horn with flags and built in summation function.

The problem of the circle above, where I ask you to justify how do you get that x+r = r*sqrt(2), let me refresh a couple of userRPL commands and the usage of flags as booleans.

I mean, the more I analyze the failures, the better.

Wikis are great, Contribute :)
