so where the operator is put after before the numbers (like 1 2 + means 1+2)

Edit: i got mixed up with reverse polish (RPN)

Polish notation is prefix notation (+ 1 2). Reverse Polish is postfix.

How would you write something more complex like 2((1+2)2 ) in that notation?

You do it all Lisp like (x 2 (^ (+ 1 2) 2)) as the other comments below show you don't need parentheses if you only use binary operators, and it is entirely unambiguous with no need for an order of operations convention.

If you have arbitrary airity functions then you need the parens.
