Answer 1

Calculando, iremos obter: $\boxed{\boxed{\begin{array}{lr}\boldsymbol{ - 2}\end{array}}}$

Expressões numéricas são calculadas da seguinte forma:

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \green{ \star}$ Eliminação:

$\boxed{\boxed{\begin{array}{lr}\mathbf{Par\hat{e}nteses > ( \: )} \\\mathbf{Colchetes > \begin{bmatrix} \: \: \end{bmatrix}} \\ \mathbf{Chaves > \begin{Bmatrix} \: \end{Bmatrix}}\end{array}}}$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \green{ \star}$ Operação:

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \green{ \star}$ Jogo de sinais:

$\boxed{\boxed{\begin{array}{lr}\mathbf{( + ) \times ( + ) = ( + )} \\ \mathbf{( - ) \times ( - ) = ( + )} \\ \mathbf{( + ) \times ( - ) = ( - )} \\ \mathbf{( - ) \times ( + ) = ( - )}\end{array}}}$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \green{ \star}$ Vamos ao seu exercício!

$\boxed{\boxed{\begin{array}{lr}\boldsymbol{8 - 9 \div 1 - 6 \div 1 + 5} \\\boldsymbol{ \: \: \: \: 8 - 9 - 6 \div 1 + 5} \\\boldsymbol{ \: \: \: \: \: \: \: \: 8 - 9 - 6 + 5} \\\boldsymbol{ \: \: \: \: \: \: \: \: \: \: \: 13 - 9 - 6} \\ \boldsymbol{ \: \: \: \: \: \: \: \: \: \: \: \: \: \: 13 - 15} \\\boldsymbol{ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: - 2} \end{array}}}$
