The answer would be 15.
First you would have to do 5 x 2 (since it is in parentheses) which would get you 10. Then you would have to do 8 - 3 (since it is also in parentheses) that would get you 5. Last you add 10 + 5 and the answer would be 15.
I'm so sorry if that was confusing or it didn't help.
