What is the reason for 0 = (R-R) + ... ?
...

The reason for the (R-R) term is to make the equation "solvable" for "R" and to have "R" in the menu following the angle (the variables appear in the order "Angle", "R", "X", "Y").

If I do not insert (R-R), the solver beeps and says that he cannot find a solution for "R" (but it shows the corect result for R) - with (R-R) it stays silent and directly shows the result for R.
Again, there may be better ways to achieve this.

[I also learned that there is an angle symbol "∡" in the character set, so I replaced the nordic Ø with that symbol)]
