I’m pretty sure cow is the species common name and bull/heffer are the sex variant terms.

You know, like how a rooster and a hen are both still chickens?

My argument is specifically that using no separation shows intent for which way to interpret and should not default to weak juxtaposition.

Choosing not to use (6/2)(1+2) implies to me to use the only other interpretation.

There’s also the difference between 6/2(1+2) and 6/2*(1+2). I think the post has a point for the latter, but not the former.

Honestly, I do disagree that the question is ambiguous. The lack of parenthetical separation is itself a choice that informs order of operations. If the answer was meant to be 9, then the 6/2 would be isolated in parenthesis.
