Answer 1

a)832:8+[40+8×(100:5-72:4)]×10=

832:8+[40+8×(20-18)]×10=

832:8+(40+8×2)×10=

832:8+(40+16)×10=

832:8+56×10=

104+560=664

b)[(36-36:2×0)+(6×7-4×9)]:7=

[(36-18×0)+(42-36)]:7=

[(36-0)+6]:7=

(36+6):7=

42:7=6

c)(36:4+4×6+8:2+2):[(36:4+3×13)-3×10-15]=

(9+15+4+2):[(9+39)-3×10-15]=

(24+6):(48-3×10-15)=

30:(48-30-15)=

30:(18-15)=

30:3=10

d)[86:2+3×(6+3×6+3)]:7-(8-3)×(31-29)=

[86:2+3×(6+18+3)]:7-5×2=

[86:2+3×(6+21)]:7-5×2=

(86:2+3×27):7-5×2=

(43+81):7-5×2=

124:7-5×2=

124:2×2=

62×2=124

e)8+3×[(3×13-4×12:6+2×11+2):5]=

8+3×[(39-48:6+22+2):5]=

8+3×[(39-8+24):5]=

8+3×[(31+24):5]=

8+3×(55:5)=

8+3×11=

8+33=41

f)90+[(45-34)×(56:8-7)]:10+3×(56-8×6)=

90+[11×(7-7)]:10+3×(56-48)=

90+(11×0):10+3×8=

90+0:10+3×8=

90:10+24=

9+24=33
