Answer 1

Respuesta:

b.-  -21

c.-  -21

d.-  -47

k.-  35

l.-  -46

Explicación:

Procedimiento de la opción b:

(–8 + 7) + [–3 + (–5 – 6)] + (–2 – 4)=?

(-1) + [–3 + (-11)] + (–6)=?

-1 + [–3 - 11] + (–6)=?

-1 + [–14] – 6=?

-1 – 14 – 6=?

-1 + [–14] – 6= -21

Procedimiento de la opción c:

–10 – 4 – [–10 + 16 – ( 3 + 2 – 5) + 3 – 2] =?

–10 – 4 – [–10 + 16 – (0) + 3 – 2] =?

–10 – 4 – [–10 + 16 – 0 + 3 – 2] =?

–10 – 4 – [7] =?

–10 – 4 – 7 =?

–10 – 4 – 7 = -21

Procedimiento de la opción d:

[–8 – 10 – (–3 + 15 – 2) + (–8 – 13)] + 2=?

[–8 – 10 – (+10) + (–21)] + 2=?

[–8 – 10 – 10 –21] + 2=?

[–49] + 2=?

–49 + 2=?

–49 + 2= -47

Procedimiento de la opción k:

{– [– (15 + 10) + (–20)]} + {5 + [(–20 + 5)]}=?

{– [– (25) + (–20)]} + {5 + [(–15)]}=?

{– [–25 – 20]} + {5 + [–15]}=?

{– [–45]} + {5 – 15}=?

{+45} + {5 – 15}=?

45 + {-10}=?

45 - 10=?

45 - 10= 35

Procedimiento de la opción l:

(36 – 24) + { – [4 + (–1 – 6) – 7] – 50} – 18=?

(12) + { – [4 + (–7) – 7] – 50} – 18=?

12 + { – [4 – 7 – 7] – 50} – 18=?

12 + { – [–10] – 50} – 18=?

12 + { + 10 – 50} – 18=?

12 + {–40} – 18=?

12 – 40 – 18=?

12 – 40 – 18= -46
