Answer 2

f)8-[5-(12-17)]=
8-[5-(-5)]=
8-(5+5)=8-10=-2

g)17-[2-(-6+15)]=
17-[2-(+9)]=
17-(2-9)=.17-7=10



h)47+[-14+(17-53)]=
47+[-14+(-36)]=
47+(-14-36)=
47-50=-7

i)-37+{-3+[5+(-21-54)]}=
-37+{-3+[5+(-75)]}=
-37+[-3+(5-75)]=
-37+[-3+(-70)=
-37+(-3-70)=-37-37=-74

j)-23+{-19-[-33+37-(-29)]}=
-23+[-19-(-33+37+29)]=

-23+[-19-(+33)]=
-23+(-19-33)=.
-23+(-52)=-23-52=-75
