1. The problem is to simplify the expression $-)(4+4(3$. 2. First, we need to clarify the expression. Assuming the expression is $- (4 + 4 \times 3)$, we follow the order of operations (PEMDAS/BODMAS): parentheses, exponents, multiplication and division (from left to right), addition and subtraction (from left to right). 3. Calculate inside the parentheses: $4 \times 3 = 12$. 4. Now the expression inside the parentheses is $4 + 12 = 16$. 5. Apply the negative sign outside the parentheses: $-16$. 6. Therefore, the simplified value of the expression is $-16$.
