Answer 2

(-9)-(-13)+(-20)+(-2)=

3+13-(-7)+6
=
(-2)-8-14-13=

(-7)+(-5)-(-8)+3=
(-11)-4-(-18)+18
=
4+(-11)-1-(-3)
=
(-17)-6-16-(-18)
=
5+7+(-1)-(-8)
=
(-1)-(-1)+15+1
=
3-(-5)-3+(-15)
=
6+(-14)-(-14)+(-13)
=
(-15)-(-13)-(-17)-(-4)
=
(-20)-13+(-7)+11
=
8+(-1)-7+(-4)
=
(-13)-(-9)+16-(-12)
=
(-1)+4+19+(-2)
=
(-17)+(-9)-20+(-6)
=
(-5)+12-(-16)-(-15)
=
(-3)-13-(-5)+13
=
5+(-7)+17-10
=
(-10)-(-16)-13-(-16) =
(-14)+4-19-12
=
-5+13+14-(-10)
=
3+(-10)-17-(-10)
=
6+(-12)+15-(-15)
=
15-(-9)-13+(-7)
=
2-(-10)+1-(-8) =
11+(-19)+(-14)-5 =
19-16+18-(-11)
=
-3+(-8)-(21)+(-7)=
(-1)-19+(-5)+1
=
-4+(-3)+9-(-30)=
(-5)+19-10-(-5)
=
11-(-17)-(-13)+12
=
(-8)+(-10)-8+17
=
9+(-8)-(-9)+6=
7-(-12)-(-1)+(-12)
=
12+12-(+19)+20
=
(-13)-(-11)+20+(-4)
=
