III.) Desarrollar las siguientes operaciones combinadas con números enteros:
8) (–8) · (+2) + (–5) · (–3) =
9) (–3) · (+9) + (–18) (–3) – (–5) · (–4) =
10) (+27) (–3) – (+3) · (–5) – (– 6) · (–2) =

Answer 1

Respuesta:

(+3) + (-2) - (-7) - (+2)

(+3) + (-2) + (+7) + (-2)

3 - 2 + 7 - 2

(-4) + (-2) - (-3) - (+4)

-4 – 2 + 3 - 4

(-7) - (-2) - (+3) + (-7)

-7 + 2 – 3 – 7 -9 – 5 + 9 - 3

(-9) + (-5) - (-9) + (-3)

(+5) - (-2) - (+3) + (-7)

5 + 2 – 3 – 7 7 + 8 – 3 + 7

(+7) - (-8) + (-3) - (-7)

(-10) + (-3) - (-9) - (+8)

-10 – 3 + 9 – 8 9 + 10 – 11 - 8

(+9) - (-10) + (-11) - (+8) eso es todo

Answer 2

Respuesta:

8) -1

9) 7

10) 84

Explicación paso a paso:

Recuerda realizar las operaciones de izquierda a derecha siguiendo el orden de las operaciones, donde en este caso tienen prioridad las multiplicaciones.

8) (–8) · (+2) + (–5) · (–3) =

(-16)+(-5)•(-3) =

(-16)+(15)=

-1

9) (–3) · (+9) + (–18) (–3) – (–5) · (–4) =

(-27)+(-18)(-3) - (-5)•(-4)=

(-27)+(54) - (-5)•(-4)=

(-27)+(54) - (20)=

(27) - (20)=

7

10) (+27) (–3) – (+3) · (–5) – (– 6) · (–2) =

(81) – (+3) · (–5) – (– 6) · (–2) =

(81) – (-15) – (– 6) · (–2) =

(81) – (-15) – (12) =

(96)– (12) =

84
