Oblicz :
(-12) + (-8) - (+7) - (-9)=
8 - (-9) + (-11) - (+5) =
(21) + (-7) - (+15) - (-32)
-(-13) + (-2) - ( + 16) + (-5)
Opusc nawiasy i oblicz:
25 - (13 + 16) =
32 - (-5 + 10 )=
14 + (-17 +4)=
-42-(56-60)=
-20 - (16-12)=
-17 + (-5 + 10)=
(6 - 10) - (-12 + 14)=
(12 - 14) - (-16 - 25)=
-(6-9) - (-12 + 15)=
Zgóry dziękuję :) Prosze niepisac samych wyników.
