Answer 1

a)81:9×(24:4+72:8-100:10-35:7)=
9×(6+9-10-5)=
9×(15-10-5)=
9×(5-5)=
9×0=
0
b)10×3-(12+72:8-4×4)×8:(2×5)=
30-(12+9-16)×8:10=
30-(21-16)×8:10=
30-5×8:10=
30-40:10=
30-4=
26
c)42:6+(21+21:3+28:4-48:6):9=
7+(21+7+7-8):9=
7+(28+7-8):9=
7+(35-8):9=
7+27:9=
7+3=
10
d)2+(100:10-18:9-36:6)×(35:5-49:7+36:4)=
2+(10-2-6)×(7-7+9)=
2+(8-6)×(0+9)=
2+2×9=
2+18=
20
e)5×10-(4×3+45:9×6):7+(6×8-81:9)=
50-(12+5×6):7+(48-9)=
50-(12+30):7+39=
50-42:7+39=
50-6+39=
44+39=
83
