The correct answer is: 11
Here’s how you solve it!
You can remove the 0 since when you add or subtract 0 it stays the same.
Then you would want to look at the first set of parentheses (-20)
Since it is -(-20) this changes the sign to a positive +20
9-5+20+(-13)
Now since the + is in front of the (-13) it remains the same.
Now you are left with this:
9-5+20-13
9-5=4
4+20=24
24-13=11
Then you are left with your answer: 11
