Answer:
The answer is B.
Step-by-step explanation:
3 times 3 is 9. 2 times -6 is -12. 9 + -12 is -3.
9 times 3 is 27. 4 times -6 is -24. 27 + -24 is 3.
It's important because changing the order of operations changes the answer
Well u have to do whats in the parenthesis first so -(5+(-11.3 equals -16.3 then u add (-4.3) so -16.3+ (-4.3) = -20.6
