Hi there! We are going to use PEMDAS. PEMDAS is Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction. First, we do what ever is in parentheses first, since (-2) is in parentheses we do that first. -6÷(-2)=3, we don't have any exponents so we move on to multiplication, we don't have any division so we move on to addition. We have addition so our problem should look like 3-6+4. 3-6=-3. Now we have -3+4, -3+4=1. Therefore, our answer is 1.
