Answer 1

Answer:

a) 16×8+4

= 128+4

= 132

b) 5x6-40+4+18

= 30-40+22

= 30-18

= 12

c) 12+3×4-6+2

= 12+12-6+2

= 24-8

= 16

d) 26+64-8-10+5×11

= 26+64-8-10+55

= 90-8+45

= 90-53

= 37

e) 45+9+10-8

= 64-8

= 56

f) 75+5+6×11-21

= 75+5+66-21

= 146-21

= 125

g) 14+2+6-41

= 22-41

= -19

h) 45-16+28+4×9+3

= 29+28+36+3

= 96

i) 12×3-42+7

= 36-42+7

= -6+7

= 1

j) 8+54+6×3-10

= 62+18-10

= 80-10

= 70

k) 50-48+6×4+5

= 2+24+5

= 31
