"Common Core Math problem" - yes, it does look like a special kind of math. Marking that answer wrong is the equivalent of "you are not allowed to think about this just yet". I sure hope that teacher at least sat him down to explain how multiplication is commutative.

Does anyone have a more sane explanation of what the goal is? I can't think of any way this is going to be helpful to the student.
