A. (–30 : 3 × 4) × {(-8) + 2(7 – 3)} b. (–60 : 3 × 4) × {3(8) + 3(6 – 13)}
c. (–45 : 3 × 4) × {-2(8) + 5(11 –23)} d.{(–3) × 4 + 3(–10)} + {(–48) : 12 + 12

Answer 1

Respuesta:

a. =(-30:12)x{(-8)+2(4)}

  =-2.5x(-8+8)

  =-2.5x0

  =0

b. =(-60:12)x(24+3(-7))

   =-5x(24-21)

   =-5x3

   =-15

c.=(-45:12)x{(-16)+5(-12)

  =-3.75x(-16-60)
