Correct Answer: D
Explanation:
Use the order of operations: PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction).
We want to solve what's in the parentheses first.
12÷(1+3)−9×6
12÷(4)−9×6
Now, do the division and the multiplication.
12÷4=3
9×6=54
Therefore our equation becomes:
3−54
Finally, subtract.
3−54=−51
