Does the commutative property change anything here? A, B and C are not constrained in any way to each other, so they can be in whatever order you want anyways...

Moreover, addition is commutative so it doesn't matter what order the division is in since a/b/c = a+b+c = c+a+b = ...

So I'd say that the model pointing this out is actually a mistake and it managed to trick you. Classic LLM stuff: spit out wrong stuff in a convincing manner.
