-13/24 because u have to multiply to get the same denominator which would end up being -15/24 and 2/24 add that to get -13/24
Answer:
Parenthesis, Exponents (& roots), Multiplication, Division, Addition, Subtraction.
This is the order you use when you need PEMDAS. For example, in this question:
(2 * 3) + 5(3)
First, you solve the parenthesis: 2 * 3 = 6
Next, you solve for multiplication: 5(3) = 15
Finally, you add: 6 + 15 = 21
