Answer 1

8)

a) 7×(5+9)=7×14=98

7×(5+9)=35+63=98

b) (12+3)×11=15×11=165

(12+3)×11=132+33=165

c) 12×(14-9)=12×5=60

12×(14-9)=168-108=60

d) (22+3-5)×7=20×7=140

(22+3-5)×7=154+21-35=140

e) 13×(982-745)=13×237=3081

13×(982-745)=12766-9685=3081

f(20×3-15×3)÷(45÷15+54÷27)=(60-45)÷(3+2)=15÷3= 3

g) (35×12-25×12)÷(45÷9+54÷18)

h) (18×19+18)÷(15×12÷5)=(342+18)÷36=

360÷36=10

9)

a) 5×9-(100-8×9)=45-(100-72)=45-28=18

b) 35×112-(2000-167×5)

c) (114×2-60)+18×3-(160-8×20)=222

d(223-42)×6-(23×2-15)×2=1024

e)25×(40-30)+48×(12-8)=442

f)(270+130)×80-30000=29000

g)(24×4-72+1234567)×(2×9-3×6)=0

h(24×3-8×9)×(15234×5829-34)=0
