C) 5-{2+(11-18) - [5+ (-4 + 1)] + 8}=

D) [-1+ (22-5×6)] ÷ (-5+ 2) + 1 =

E) [-(24-8)× 2-24] ÷ [22- (-3+2)] =
​

Answer 1

Explicação passo-a-passo:

[(18+ 3×2) ÷ 8 + 5×3] ÷ 6

[(18+ 6) ÷ 8 + 5×3] ÷ 6

[24 ÷ 8 + 5×3] ÷ 6

[3 + 5×3] ÷ 6

[3 + 15] ÷ 6

18 ÷ 6

- 7+ {- 5+ [(8-12) + (15+12)] -10}

- 7+ {- 5+ [-4 + (15+12)] -10}

- 7+ {- 5+ [-4 + 27] -10}

- 7+ {- 5+ 23 -10}

- 7+ {18 -10}

-7+8

5-{2+(11-18) - [5+ (-4 + 1)] + 8}

5-{2+(11-18) - [5+ (-3)] + 8}

5-{2+(11-18) - [5-3] + 8}

5-{2+(-7) - [5-3] + 8}

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

5-{2-7 - 2 + 8}

5-{-5- 2 + 8}

5-{-7 + 8}

5-{1}

5-1

4

[-1+ (22-5×6)] ÷ (-5+ 2) + 1

[-1+ (22-30)] ÷ (-5+ 2) + 1

[-1+ (-8)] ÷ (-5+ 2) + 1

[-1-8] ÷ (-5+ 2) + 1

[-1-8] ÷ -3 + 1

-9÷-3+1

3+1

4

[-(24-8)× 2-24] ÷ [22- (-3+2)]

[-16× 2-24] ÷ [22- (-3+2)]

[-16× 2-24] ÷ [22- (-1)]

[-16× 2-24] ÷ [22+1]

[-32-24] ÷ [22+1]

-56 ÷ 23

-2,43...
