Răspuns:

c)

-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
