RE: 5 minus minus 6 on in HOME and CAS
It isn't allowed in home, and we'd have completely removed it from the CAS if possible. This type of construct does not belong in a math focused *calculator*. The problem is, ++ -- is deeply down in the CAS parser and we couldn't remove it.

Try explaining something like --4+++5++ to a student and why it would be valid... (it would be in the HOME parser/evaluation if we enabled increment/decrement type operators)

While in a *programming* language they might make sense, on a calculator that is primarily focused on *math* they do not. Not all languages allow them either because they can introduce confusion, and don't really gain you anything other then a few less characters to type.

They are not documented because we don't want it being used.
