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

The parenthesis are pointless. Exponents go first, but multiplication doesn’t care about order, and there is only multiplication going on.

Clarification of what? The joke doesn’t need them and neither does the math.

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?

No, it is syntactically unnecessary.
I understand your point, and agree when it comes to programming and scope, typing, semicolons, etc, etc… Many things are easier to learn when enforced through syntax.
Though if someone gets cofused on the transitive nature of multiplication with a single simple equation … They aren’t learning math.

They could be used to separate two letter symbol (Pi) from one letter symbol (Z, Z, a)
