>It does depend on your use case.

Yes, and the first line's use case depends on the language built-in operator precedence rules to reduce the number of parens.

If you are using math formulas as an example of minimal paren usage, go with APL and have even fewer since all operators are equal precedence and associate to the right.

If you really wanted to write the quadratic formula (or math formulas in general) you could use APL and use even fewer.
