For a certain value of '"proper" [tm] rules of mathematics' that is=20
certainly true. The trouble is in deciding that rules.

AFAIK in my 'basic' school (6-12y) I was told that multiplication has=20
precedence over division. In high school (12-18y) I recall them having=20
equal precedence, and to evaluate left-to-right. And the wiser of te=20
teachers discouraged writing anything that could be interpreted=20
differently depending on whether multiplication was to have precedence=20
(over division) or not, for instance by using the horizontal bar instead=20
of the /.

APL btw evaluates strictly from right to left!
