<h3>Procedure - Application of hierarchy rules in a arithmetic expression</h3>
In this question we should make use of hierarchy rules represented by the use of parentheses. The parentheses oblige to make operations inside it before making it in the rest of the formula.
Now we decide to add parenthesis in the component such that the result of the entire expression is 48. We proceed to present the proof:
Adding parentheses in the component of the expression may bring an output of 48. 
<h3>Remarks</h3>
The statement presents mistakes and is poorly formatted. Correct form is shown below:
