This is a different situation because / is indeed an hidden multiplication : a/b = a*inv(b). The same is true for + and - : a-b=a+opp(b). What I'm saying is that these operations * and / are indeed of the very same j-kind.

This is not the same for * and @.

This doesn't follow.  (a / b) * c != a / (b * c), but / and * in
Python have the same priority.
