Explicación paso a paso:

i. –2 – {–2 – [–2 – (–2 – 2) – 2] – (–2 – 2)} – 2

–2 – {–2 – [–2 – (-4) – 2] – (-4)} – 2

–2 – {–2 – [–2  (+4) – 2] – (-4)} – 2

–2 – {–2 – [–8 – 2] – (-4)} – 2

–2 – {–2 – [–10] – (-4)} – 2

–2 – {–2 + 10 +4} – 2

–2 – {12} – 2

–2 - 12 – 2

-16

j. 26 – {(–32) – [29 + (–24)] – (–12 + 20)}

26 – {(–32) – [29 –24] – (8)}

26 – {(–32) – [5] – 8}

26 – {–32 – 5 – 8}

26 – {-45}

26 + 45

71

k. {–[–(15 + 10) + (–20)]} + {5 + [(–20 + 5)]}

{–[–(25) –20]} + {5 + (-15)}

{–[–25 –20]} + {5 -15}

{–[-45]} + {-10}

{+45}  - 10

45 - 10

35

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
