5+3(-2-7)-(-2+1) - Multiply 3 by what is in the parenthesis.
5+(-6)-21-(-2+1) - -2+1 is -1
5+(-6)-21-(-1) - 5+(-6) is -1
-1-21-(-1) - -1-21 is -22
-22-(-1) - 2 Negatives = a positive
-22 +1
-21
5+(-6)-21-(-2+1) - -2+1 is -1
5+(-6)-21-(-1) - 5+(-6) is -1
-1-21-(-1) - -1-21 is -22
-22-(-1) - 2 Negatives = a positive
-22 +1
-21

5 plus multiply 3X-2 plus multiply 3X-7 plus minus minus 1. (minum minus 1 is plus 1)
5-6-21+1
6-27 combine pluses and minuses
ans: -21

5 + 3 times (- 2 - 7 ) - ( - 2 + 1)
3 times ( - 2 - 7 ) = 3 ( - 9 ) = - 27
- ( - 2 + 1 ) = - ( - 1 ) = + 1
5 + - 27 + 1 = + 6 - 27 = - 21
3 times ( - 2 - 7 ) = 3 ( - 9 ) = - 27
- ( - 2 + 1 ) = - ( - 1 ) = + 1
5 + - 27 + 1 = + 6 - 27 = - 21

The rules are to do the stuff in parentheses first, then multiplication, then addition/subtraction.
