This is a great question for PEMDAS
Parenthesis
Exponents
Multiplication and Division
Addition and Subtraction
Let's start off with the parenthesis.
Parenthesis:
(9÷3)+4(6-7)
We have two sets of parenthesis.
9÷3=3
6-7=-1
Let's replace the parenthesis.
3+4(-1)
There are no exponents.
Let's look at multiplication.
3+4(-1)
4×-1=-4
Let's look at addition.
3+-4=-1
So B. -1.
