Resuelve paso a paso aplicando la jerarquía de solución.
(5-3)x[(-6)+(5+1)-(-5)]-[(5+6)-(-7+9)-(-2)]=
(-5+7-3)-[(-5+13)+(-3-1)+(4-5)+9x(-5)]=
(-7-8)[-4)+(-4+2)-(+9)]-[(3+10)-(-18+9)+(-3)]=​

Answer 1

Explicación paso a paso:

1) (5-3)x[(-6)+(5+1)-(-5)]-[(5+6)-(-7+9)-(-2)]

( 2 )x[(-6)+ 6 + 5)]-[( 11 )-( 2 ) + 2)]

2 x 5 - 11 = - 1

2) (-5+7-3)-[(-5+13)+(-3-1)+(4-5)+9x(-5)]

- 1 -[ 8 - 4 - 1 + 9 x (-5)]

- 1 -[ 8 - 4 - 1 - 45 ]

- 1 + 42 = 41

3) (-7-8)[-4)+(-4+2)-(+9)]-[(3+10)-(-18+9)+(-3)]

(−15)(−4)−4+2−9−(3+10−(−18+9)−3)

60−4+2−9−(3+10−(−18+9)−3)

60−2−9−(3+10−(−18+9)−3)

58−9−(3+10−(−18+9)−3)

49−(3+10−(−18+9)−3)

49−(13−(−18+9)−3)

49−(13−(−9)−3)

49−(22−3)

49−19 =30
