a)(18+2x7):(12:2+8:4)

(18+14):(6+2)

32:8=4

b)24-24:3x(72:9-2x3):4x5

24-24:3x(8-6):4x5

24-8x2:4x5

24-16:4x5

24-4x5

24-20=4

c)36:6+4x2x5-(20-12:3).

36:6+4x2x5-(20-4)

36:6+4x2x5-16

6+8x5-16

6+40-16

46-16=30

d)42:7+(6+6):2-24:(5+3)

42:7+12:2-24:8

6+6-3=9

e)(25+20):5-(19+5):8

45:5-24:8

9-3=6

F)10+(10:10+10)-(10x1+10)

10+(1+10)-(10+10)

10+11-20

21-20=1
