Explanation:
To solve problems like this, use PEMDAS. Parentheses, Exponents, Multiplication, Division, Addition, Subtraction. These are the order in which you solve a problem. So, first, you would solve what's inside the parentheses. Then, you would take 30 and subtract nine (the solution of three times three.). From there, take the difference and add four to it. That gives you 25.
