Final answer:
To solve the expression (6 + 3) + (4-5), simplify the parentheses and use the order of operations. The final answer is 8.
Step-by-step explanation:
To solve the expression (6 + 3) + (4-5), we use the order of operations, also known as PEMDAS. We start by simplifying the parentheses in the expression. In the first set of parentheses, 6 + 3 equals 9. And in the second set of parentheses, 4-5 equals -1. Now we substitute the simplified values back into the original expression, giving us 9 + (-1). Finally, we add the two numbers together to get the final answer, which is 8.
