Follow the order of operations. Multiplication and division being Equal to each other you’ll need to go from left to right just like you are reading a book.
(-8)+(-3)+ (-28) / 14+9 (-2)
(-8)+(-3)+ (-2)+9 (-2)
(-8)+(-3)+(-2)+(-18)
Then once all multiplication and division is completed you can move on to addition and subtraction. Same as before left to right.
-11+ (-2)+(-18)
-13+ (-18)
-31 is the answer
