Răspuns:
20-[(-5)+6+(7-2)+(-3)]= 20-( 1+5-3)=20-3=17
1-{14-[2-(-5)+(-3)+(-5)]}=1-[14-(2+5-3-5)]=1-[14-(-1)]=1-(14+1)=1-15= -14
-3+[(-3)+(-2)+3]+[(-2)-5]= -3+(-2)+(-7)= -3-2-7= -12
-5+{[(-3)-(-2)-(8-10)]-3}= -5+{[(-1)-(-2)]-3}= -5+[(+1)-3]= -5+(-2)= -7
[-13+(5-2)]+{4+[(-10)+5]-3}=(-13+3)+[4+(-5)-3]=-10+(-4)= -14
(18-8)+[-5+(-4)+14]-6=10+[(-9)+14]-6= 10+5-6=9
