@kohn Ironically (if German typographic conventions are similar to those I know), the question should use a hyphen instead of an en dash, and lose the space on its left side:
"Plus- und Malaufgabe"
@samgai @kohn maybe a comma went missing at it's supposed to be something like "plus minus und malaufgabe"
@eichkat3r @kohn So the answer should also include 5 - (-5) - (-5) - (-5) = 20?
