Let is definitely valid, but I’m leaning towards ${} being the one that doesn’t fit for arithmetic.

I think $[] is also a way to evaluate expressions, but I can't recall if it's still used in modern scripts.

I’m not sure about ${}, but I feel like it’s more for variable expansion than arithmetic.

I remember practicing with arithmetic expressions, and I think $(( )) is definitely valid.
