Oblicz:
(13+8)*(-2)
(3-7)*(15-6)
(17-5):(-3)
-23-4:-28+19
(-5)*2*(-7)
(-3)*(-2)*(-7)
(-3)*(-2)*(-4)
PROSZEEE!!!!!!!!!!!

(13+8)*(-2) = 21*(-2)= (-42)
(3-7)*(15-6) = (-4)*9 = (-36)
(17-5):(-3) = 12:(-3) = (-4)
-23-4:-28+19 = -27:-9= 3
(-5)*2*(-7) = -10*(-7) = 70
(-3)*(-2)*(-7) = 6*(-7) = -42
(-3)*(-2)*(-4) = 6*(-4) = -24
Please. ;)
(13+8)*(-2)=21*(-2)=-42
(3-7)*(15-6)=-4*9=-36
(17-5):(-3)=12:(-3)=-4
chyba zapomniałaś o nawiasach bo gdyby były to wynik będzie inny gdyż najpierw trzeba by podzielić
-23-4:-28+19=-27:-9=3
(-5)*2*(-7)=-10*(-7)=70
(-3)*(-2)*(-7)=6*(-7)=-42
(-3)*(-2)*(-4)=6*(-4)=-24
