Answer 1

a) - 2 + 3 × 5 = - 2 + 15 = 30

b) - 7 + 4 × ( - 2 ) = - 7 - 8 = - 15

c) - 2 - 10 : ( - 5 ) = - 2 + 2 = 0

d) - 6 - 12 : ( + 3 ) = - 6 - 4 = - 10

e) - 7 + ( - 2 ) × ( - 9 ) = - 7 + 18 = 11

f) - ( - 5 ) + ( - 24 ) : ( - 8 ) = 5 + 3 = 8

g) 12 - ( - 20 ) × ( - 2 ) = 12 + 20 × ( - 2 ) = 12 - 40 = - 28

h) 18 - 49 : ( - 1 ) = 18 + 49 = 67

i) 5 - 60 : 3 = 5 - 20 = - 15
