> * Another thing to keep in mind is the combined unit field where the first token that is neither a number, nor an operator or a parenthesis is taken...

> * For the answer type Algebraic formula, I think we cannot simply disallow `e` as a variable, as that could break compatibility for existing questions, see above regarding the...

> * Maybe there is even a possibility to extend the idea above to the teacher's side, i. e. as soon as they define a _variable_ `e` in their question,...

Hello Philipp, I just want to share my point of view, which may differ from yours. Let’s hope that some clarity will emerge from our discussion. My tone is direct...
