Consider the infix expression $\frac{8+2}{5}+2$

a$.(30)$ In order to evaluate the expression it must be converted to Postfix notation.

First describe the process$/$rules of performing the conversion.

Then use that process to convert the above expression to postfix.

Note that if you don't remember exactly how to process parenthesis, simply process them in a separate area until you get to the end of the parenthesized part of the expression. Then convert the expression to Postfix.
