b) 37 + [-25 – (-11 + 19 – 4)] =

c) -8 + {-5 + [(8 – 12) + (13 + 12)] – 10} =

d) [-1 + (22 – 5 · 6)] ÷ (-5 + 2) + 1 =

e) 60 ÷ {2 · [-7 + 18 ÷ (-3 + 12)]} – [7 · (-3) – 18 ÷ (-2) + 1] =

Answer 1

Resposta:

a) [(18 + 3 · 2) ÷ 8 + 5 · 3] ÷ 6 =

[24 ÷ 8 + 5 · 3] ÷ 6

3+15÷ 6

18÷ 6

3

b) 37 + [-25 – (-11 + 19 – 4)] =

37 + [-25 +6]

37-19

18

c) -8 + {-5 + [(8 – 12) + (13 + 12)] – 10} =

-8 + {-5 + [-4+25]- 10}

-8 + {-5 +21- 10}

-8 +6

-2

d) [-1 + (22 – 5 · 6)] ÷ (-5 + 2) + 1 =

[-1 – 8]÷ (-3)  + 1 =

-9÷ (-3)+ 1 =

3+ 1 =  4

e) 60 ÷ {2 · [-7 + 18 ÷ (-3 + 12)]} – [7 · (-3) – 18 ÷ (-2) + 1] =

60 ÷ {2 · [-7 + 18 ÷ (+ 9)]} – [-21 + 9] =

60 ÷ {2 · [+ 2)]} – [-12 ] =

60 ÷ + 8 – [-12 ] =

60 ÷ + 20 =

c) -8 + {-5 + [(8 – 12) + (13 + 12)] – 10} =

-8 + {-5 + [-4+25]- 10}

-8 + {-5 +21- 10}

-8 +6

-2

d) [-1 + (22 – 5 · 6)] ÷ (-5 + 2) + 1 =

[-1 – 8]÷ (-3) + 1 =

-9÷ (-3)+ 1 =

3+ 1 = 4

e) 60 ÷ {2 · [-7 + 18 ÷ (-3 + 12)]} – [7 · (-3) – 18 ÷ (-2) + 1] =

60 ÷ {2 · [-7 + 18 ÷ (+ 9)]} – [-21 + 9] =

60 ÷ {2 · [+ 2)]} – [-12 ] =

60 ÷ + 8 – [-12 ] =

60 ÷ + 20 =
