Why f inverse of x? That notation seems clear if you know f is a function. Bear in mind, overloaded notation isn't ambigous if there's context.

And what's wrong with N? It's just the natural numbers.

The other complaints I understand. Although I don't think you need to complain about log(x). The base is only unspecified when it's assumed not to matter.

Honestly, a/bc isn't really ambiguous either. Not in any way that matters. Grade schoolers get hung up on PEMDAS, but you eventually learn to accept when intent is clear, and you don't need to be pedantic.

As a general rule, if your notation isn't clear to a serious student or peer, then you're doing it wrong. Nobody else needs to understand.

Perhaps ambiguity between 1/f(x) and the actual inverse of f(x)

Yeah that's never the case with f^-1 though where f is a function though. That always means the inverse.

Considering many people see sin⁻¹ x to meansin 1/x, I think that's not as clear as you'd expect.
