    The parentheses are for clarification and thus not pointless. Know your audience. 🙂👍

        That Z² is equal to ZZ.

        If we didn’t use parentheses in primary school, because “the math doesn’t need it”, then it would be quite unnecessarily hard on the students’ learning. Maybe it’s a joke someone made for a class?
