Answer 1

Respuesta:

Explicación paso a paso:

a)-3×(-2) + [7 - (+3)]= +6 + (7-3)= 6 + 4= 10

B) [-2-(-3)]×2-4= (-2+3) x 2-4= 1 x 2 -4= 2-4= -2

c) 2×(-3) -4× (2-5-1)= -6 -4 x (-4)= -6 + 16 = 10

D) -(5-7) ×2-4 :(-1)= -(-2) x 2 +4= -4 + 4= 0

E) -3×(-3) + 27:(-3)= +9 - 9= 0

F) 2× [-1-(+4)] -6×2= 2 x (-1-4) -12= 2 x (-5) -12= -10 -12= -22

G)-5× (-2) + 25: (-5) = +10 -5= 5

H) 4× (-3)-5×(-2) = -12 +10= -2

I) – 16 : (+2)-4×(-2)= -8 +8= 0

J) [(-5)×(-2)+(-6)]×2–10= ​ (+10 -6) x 2 -10= 4 x 2 -10= 8 -10= -2
