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)
