Postfix and prefix forms do not require parentheses to express the order of operations because the order is implied by the position of the operator in relation to the operands. This makes them easier to read and less prone to errors caused by missing or misplaced parentheses. While they do follow rules of operator precedence and associativity, those are true for all forms of expressions in programming languages. Additionally, both postfix and prefix forms do allow for unary operators.
