Resolva a operação:

5) 60÷{2×[-7+18÷(-3+12)]}-7[7×(-3)-18÷(-2)+1]=​

Answer 1

60 ÷ {2 . [- 7 + 18 ÷ (- 3 + 12)]} - 7 . [7 . (- 3) - 18 ÷ (- 2) + 1]

60 ÷ {2 . [- 7 + 18 ÷ 9]} - 7 . [- 21 + 9 + 1]

60 ÷ {2 . [- 7 + 2]} - 7 . [- 11]

60 ÷ {2 . [- 5]} + 77

60 ÷ {- 10} + 77

Answer 2

Resposta:

60÷{2×[-7+18÷(-3+12)]}-7[7×(-3)-18÷(-2)+1]=​

60÷{2x[-7+18÷(9)]} - 7[-21+9+1]

60÷{2x[-5]} - 7[-11]

60÷{-10} - 7 - 11

-6 - 7 - 11 = -24
