////////////////////////////////////////////////////////////////////////////////////////////////////

Calcular a expressão entre parênteses:

[- 7 + (9) (- 11)]: -106

= - 106 - ( - 1) / ( - 5)

Multiplicar e dividir da esquerda para a direita:

( - 1) / ( - 5): $\frac{(- 1 )}{(- 5)}$

$= - 106 - \frac{(-1)}{(-5)}$

Somar e subtrair da esquerda para a direita:

$- 106 - \frac{(-1)}{(-5)} : - \frac{531}{5} \\\\= - \frac{531}{5}$
