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 @. 2014-03-18 17:53 GMT+01:00 Nathaniel Smith <njs@pobox.com>:

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