A = [-5-(-8)]x(-2)= [-5+8]x(-2)
= 3 x (-2) = -9
B= 26-(-9)x1,5-0,5= 26-(-13.5) -0.5
= 26 +13.5 -0.5
= 26 + 13 = 39
C=26:(-3-2x5)= 26: (-3-10)
= 26: (-13)= -2
D=(-4)x0,278x(-2)x5x(-2,5)
= -10 x 10 x 0.278
= -100x0.278= -27.8
E=(-10)x(-8,5)x0x(-1,5)x(-2,5)
= -15 x 0 x(-2.5)
= 0x(-2.5) = 0
F=(-5)x(-8)x(-125)x(-2)x(-1)x(-0,5)
= 10 x 4 x 125
= 10x 500= 500
Voilà;) Niinii:)
