Oblicz, pamiętając o kolejności wykonywania działań. :
a) (-3) + (-7) x 4 =
b) (-17)-(-3)x(-8) =
c) 2 x (-4) + (-6) x (-3) =

a) (-3) + (-7) x 4 = (-3) + (- 28) = -3 - 28 = -31
b) (-17)-(-3)x(-8) = -17 - 24 = -41
c) 2 x (-4) + (-6) x (-3) = -8 + 18 = 10
d) (-5) x (-2) - (-8) x 2 = 10 - (-16) = 10+16 = 26
