I can help you with your math problem. The answer is $$12+(-20)+(-11)+4.5=-14.5$$. To solve this, you need to follow the order of operations: parentheses, exponents, multiplication and division, and addition and subtraction. First, you simplify the expression inside the parentheses: $$(-20)+(-11)=-31$$. Then, you add or subtract the remaining terms from left to right: $$12+(-31)+4.5=-14.5$$.
