Answer 1

¡Hola!

Aquí los resultados a tus preguntas:

a) = -15

b) = -8

c) = -19

d) = -14

Procedimiento paso a paso:

a)

$\left(12\right)-\left(17\right)+\left(-28\right)-\left(-43\right)-\left(38\right)-\left(-13\right)$

$-5+\left(-28\right)-\left(-43\right)-\left(38\right)-\left(-13\right)$

$-5-28-\left(-43\right)-\left(38\right)-\left(-13\right)$

$-33-\left(-43\right)-\left(38\right)-\left(-13\right)$

$-33+43-\left(38\right)-\left(-13\right)$

$10-\left(38\right)-\left(-13\right)$

$-28-\left(-13\right)$

$-28+13$

$-15$

b)

$\left(25\right)+\left(-38\right)-\left(-14\right)-\left(37\right)+\left(-18\right)-\left(-46\right)$

$\left(25\right)-38-\left(-14\right)-\left(37\right)+\left(-18\right)-\left(-46\right)$

$-13-\left(-14\right)-\left(37\right)+\left(-18\right)-\left(-46\right)$

$-13+14-\left(37\right)+\left(-18\right)-\left(-46\right)$

$1-\left(37\right)+\left(-18\right)-\left(-46\right)$

$-36+\left(-18\right)-\left(-46\right)$

$-36-18-\left(-46\right)$

$-54-\left(-46\right)$

$-54+46$

$-8$

c)

$-5-\left(8-9+\left(-3+7\right)+14-2\right)-\left(-8+3+10-6\right)$

$-5-15-\left(-8+3+10-6\right)$

$-5-15-\left(-1\right)$

$-19$

d)

$-8-\left(-7+12-6+9\right)+\left(-11+8-\left(6-2+4\right)+13\right)$

$-8-8+\left(-11+8-\left(6-2+4\right)+13\right)$

$-8-8+2$

$-14$

Espero haberte ayudado.

¡Saludos!.

Respuesta:

a) ( + 12 ) - ( + 17 ) + ( - 28 ) - ( - 43 ) - ( + 38 ) - ( - 13 ) =

+ 12 - 17 - 28 + 43 - 38 + 13 =

+ 68 - 83 =

- 15

b) ( 25 ) + ( - 38 ) - ( - 14 ) - ( 37 ) + ( - 18 ) - ( - 46 ) =

+ 25 - 38 + 14 - 37 - 18 + 46 =

+ 85 - 93 =

- 8

c) - 5 - ( 8 - 9 + ( - 3 + 7 ) + 14 - 2 ) - ( - 8 + 3 + 10 - 6 ) =

- 5 - ( 8 - 9 + ( + 4 ) + 14 - 2 ) - ( - 14 + 13 ) =

- 5 - ( 8 - 9 + 4 + 14 - 2 ) - ( - 1 ) =

- 5 - ( + 26 - 11 ) + 1 =

- 5 - ( + 15 ) + 1 =

- 5 - 15 + 1 =

- 20 + 1 =

- 19

d) - 8 - ( - 7 + 12 - 6 + 9 ) + ( - 11 + 8 - ( 6 - 2 + 4 ) + 13 ) =

- 8 - ( - 13 + 21 ) + ( - 11 + 8 - ( + 10 - 2 ) + 13 ) =

- 8 - ( + 8 ) + ( - 11 + 8 - ( + 8 ) + 13 ) =

- 8 - 8 + ( - 11 + 8 - 8 + 13 ) =

- 8 - 8 + ( - 19 + 24 ) =

- 8 - 8 + ( + 5 ) =

- 8 - 8 + 5 =

- 16 + 5 =

- 11
