Răspuns:

a) (7+203)÷2+[250-(76×1+9)]=

210÷2+[250-76+9]=

15+[174+9]=

15+183=

=198

b) [(357÷7+344÷8)÷2]×31+17-(500÷4+7)=

[(51+43)÷2]×31+17-(125+7)=

[94÷2]×31+17-132=

47×31+17-132=

1457+17-132=

1474-132=

=1342

c) (30×5+30)÷10+639÷9-[25×(39-10×2)]=

(150+30)÷10+71-[25×(39-20)]=

180÷10+71-[25×19]=

18+71-475=

89-475=

=-386

d) (57×2÷3)+32×450-[39×(4+2)÷2]+8=

(114÷3)+32×450-[39×6÷2]+8=

38+32×450-[234÷2]+8=

38+14400-117+8=
