Answer 1

3.a)24+12:6=24+6=30
(24+12):6=36:6=6
b)6×8+2=48+2=50
6×(8+2)=6×10=60
c)28:4+3=7+3=10
28:(4+3)=28:7=4
d)32+32:8=32+4=36
(32+32):8=64:8=8

4. a)(18+2×7):(12:2+8:4)=(18+14):(6+2)=32:8=4
b)24-24:3×(72:9-2×3)=24-8×(8-6)=24-8×2=24- 16=8
c)36:6+4×2×5-(20-12:3)=6+40-(20-4)=46-16=30
d)42:7+(6+6)2-24(5+3)=6+12:2-24:8=6+6-3=12-3=9
e)(25+20):5-(19+5):8=45:5-14=9-14=-5
f)10+(10:10+10)-(10×1+10)=10+(1+10)-(10+10)=10+11-20=21-20=1
