WebA similar algorithm applies for pre-fix expressions. Infix expressions (with or without brackets) are trickier to evaluate, since you need to incorporate precedence ordering rules for the different operands. Details omitted. The Java language expects expressions to be infix. The Java compiler converts the infix expression to postfix.
