Answer 2

Răspuns:

Explicație pas cu pas:

a)  84 - 8 × 5 + 25 = 84 - 40 + 25 = 44 + 25 = 69

b)  25 + 40 : 4 × 6 = 25 + 10 × 6 = 25 + 60 = 85

c)  8 × 8 : 8 + 8 = 64 : 8 + 8 = 8 + 8 = 16

d)  66 : ( 4 × 4 - 4 : 4 - 4 × 4 : 4) = 66 : ( 16 - 1 - 4 ) = 66 : 11 = 6

e)  70 : ( 4 × 4 - 4 : 4 - 4 : 4) = 70 : ( 16 - 1 - 1 ) = 70 : 14 = 5

f)  6 + ( 6 × 6 : 6 - 6 ) × 6 = 6 + ( 6 - 6 ) = 6 + 0 × 6 = 6 + 0 = 6

g) ( 15 + 60 : 10 ) - 3 × 7 = ( 15 + 6 ) - 21 = 21 - 21 = 0

h) ( 40 + 20 × 3 ) - 120 : 10 = ( 40 + 60 ) - 12 = 100 - 12 = 88
