Answer 1

Răspuns:

a) - 9 + |- 3| + 5

= - 9 + 3 + 5

= - 6 + 5 = - 1

b) |+ 3| + (- 7) + |- 4|

= 3 - 7 + 4

= - 4 + 4 = 0

c) |3 + 5| + (- 10)

= 8 - 10 = - 2

d) - 15 + |- 7 + 12|

= - 15 + 5 = - 10

e) - 3 + |- 4 + 8| + |- 3 + 5|

= - 3 + 4 + 2

= 1 + 2 = 3

f) - 25 + |- 12 + 70 - 8|

= - 25 + |58 - 8|

= - 25 + 50 = 25
