Answer:
1
Step-by-step explanation:
parenthesis tell you to solve whatever is inside first.
Ex. (2+3)-2=(5)-2
In this problem you would solve the (3-1) and (1-2) and you get the equation
(2)+(-1)
Now you can just solve like a normal addition problem. Keep in mind the negative sign in front of the number 1.
2+(-1)=1
This can also be rewritten as 2-1 because we are adding a negative number.
(I kept the parenthesis on the -1 so it would be easier to see)
