It's not imprecise. Any brackets (correctly) placed in that equation can be removed because they're trivial. If anyone gives an answer except 7 it's not the fault of the equation for being imprecise, poorly written or ambiguous, but entirely the failing of the person giving the answer. It's math at its most basic level.

Incidentally, you placed the brackets wrong.
