This is the way you can easily do it
1- First add all positive integers
2- sum of positive integer 1+2+1+9+2 = 15
3- Second add all negative integers
4- sum of all negative integers = -3-3-1-1 = -8
5- finally 15-8 = 7
6- that is answer

Look for ways to divide it up which makes it easier.
1+2-3+1-3+9-1+2-1 =
(1+2-3) + (1-3+9) + (-1+2-1) =
0 + (10 - 3) + 0 =
You should be able to finish it off now.
1+2-3+1-3+9-1+2-1 =
(1+2-3) + (1-3+9) + (-1+2-1) =
0 + (10 - 3) + 0 =
You should be able to finish it off now.
