Answer 1

-2+{-1+[5-3×11:3]-35}
-2+{-1+[5-33:3]-35}
-2+{-1+[5-11]-35}
-2+{-1+[-6]-35}
-2+{-1-6-35}
-2+{-42}
-2-42
= -44

Answer 2

-2+{-1+[5 -3 × (10 +1):3]-5 × 7}=

- 2 + {- 1 + [ 5 - 3 × 11 : 3] - 35}

- 2 + {- 1 + [ 5 - 33 : 3] - 35}

- 2 + {- 1 + [ 5 - 11] - 35}

- 2 + {- 1 + [ - 6] - 35}

- 2 + {- 1 - 6 - 35}

- 2 + { - 7 - 35}

- 2 + { - 42}

-2 - 42

- 44
