-1+3+{+1-3-5+[-7-4+5+(-6+2-4)]}=
-1+3+[+1-3-5+(-7-4+5-8)]=
-1+3+(+1-3-5-14)=
-1+3-21=-19
d)
10-6+8+{+3-6-5+[-1+4-3+(-7+5-2)]}=
10-6+8+[+3-6-5+(-1+4-3-4)]=
10-6+8+(+3-6-5-4)=
10-6+8-12=0
e)
-2+9+{-6+4-3+[+5-3-6+(+7-9-1)]}=
-2+9+[-6+4-3+(+5-3-6-3)]=
-2+9+(-6+4-3-7)=
-2+9-12=-5
f)
-7+2+5+{-1+4-2+[-3+6-5+(-9+8-2)]}=
-7+2+5+[-1+4-2+(-3+6-5-3)]=
-7+2+5+(-1+4-2-5)=
-7+2+5-4=-4
