As a lover of prefix and postfix notation, there is an unambiguous parsing of each of those that does not deepened on any order of operations. Neither lisp nor forth have the question at all - you can only write it exactly as you mean it.

    (- (expt 3 2))

is always -9 without needing to ask which has higher precedence.

    (expt -3 2)

is likewise always 9. There is no question if - is a binary or unary operator in prefix notation and what its order of operation should be.

Likewise, in dc

    3 _ 2 ^ p
    _3 2 ^ p

and

    3 2 ^ _ p

where '_' is the negation operator (it can be used for writing -3 directly as _3, but _ 3 is a parse error) return their results without any question of order of operations.

When you start touching infix, you get into https://en.wikipedia.org/wiki/Shunting_yard_algorithm which was not a fun part of my compiler class.

(And yes, I do recognize your credentials ... I still think that lisp and forth (above examples for dc) are better notational systems for working with computers even if it takes a bit of head wrapping for humans).
