Answer 1

1. 9x5+3x7-20:2=
=45+21-10=
=66-10=
=56
2. 8×6-16:2+60:3=
=48-8+20=
=40+20=
=60
3. (3+3)×10:6+90=
= 6x10:6+90=
=60:6+90=
=10+90=
=100
4. 24+(24:4+4):2-12=
=24+ (6+4):2-12=
=24+10:2-12=
=24+5-12=
=29-12=
=17
5. 16+36:4+2×8-27=
= 16+9+18-27=
=25+18-27=
=43-27=
=16
6.  90-42:(28+16-38)=
=90-42: (44-38)=
=90-42:6=
=90-7=
= 83
7. 22+2+2:2-10:2=
=22+2+1-5=
=24+1-5=
=25-5=
=20
8. (24:8+27)-(6×4-4)=
= (3+27)-(24-4)=
=30-20=
=10
