d. {- 5 – [- 2 + (-1 + 8)]}
e. – 6 {- 4 + 8 – [+5 (-7 + 6 – 3)] + 1 – 8}

Answer 1

a. – { -3 + [ -8 – (+4 – 6) -5] + 2}

- { -3 + [ -8 - +10 - 5] + 2}

- {- 3 + -8 - 5 + 2

+ -11 - 7

b. -2 – {- [2 + (-5 + 8) – 4] + 3}

-2 - {- [2 + 13 - 4] + 3}

-2 + [16 - 4] + 3

-2 + 12 + 3

c. 8 + {- 5 – [ -7 + (8 – 6) – 3] + 6}

8 + { - 5 - [- 7 + 2 - 3] + 6}

8 + { - 5 + 6 + 6 }

8 - 11 + 6

8 - 17

-9

d. {- 5 – [- 2 + (-1 + 8)]}

{- 5 - [- 2 + 7 ]}

- 5 + 9

e. – 6 {- 4 + 8 – [+5 (-7 + 6 – 3)] + 1 – 8}

- 6 {- 4 + 8 - [+ 5 -4] + 1 - 8}

- 6 {- 4 + 8 - 1 + 1 - 8}

- 6 - 12 - 2 - 8
