8 - 4 + 1 + 3 + 5 = 13

Espero ter ajudado.

Answer 2

O valor da expressão numérica será: $\boxed{\boxed{\begin{array}{lr}\boldsymbol{13}\end{array}}}$

• Eliminação:

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

• Operação:

$\boxed{\boxed{\begin{array}{lr}\boldsymbol{Potenciac_{\!\!\!,}\tilde{a}o > x {}^{2} } \\ \boldsymbol{Multiplicac_{\!\!\!,}\tilde{a}o \: e \: divis\tilde{a}o > \times/ \div}\\ \boldsymbol{Adic_{\!\!\!,}\tilde{a}o \: e \: subtrac_{\!\!\!,}\tilde{a}o > +/ - }\end{array}}}$

• Jogo de sinais:

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

• Seu exercício:

$\boxed{\boxed{\begin{array}{lr}\boldsymbol{8 - 4 + 1 + 3 + 5} \\ \boldsymbol{ \: \: \: \: \: \: \: \: 9 + 3 + 5} \\ \boldsymbol{ \: \: \: \: \: \: \: \: \: \: \: 12 + 5} \\\boldsymbol{ \: \: \: \: \: \: \: \: \: \: \: 17 - 7} \\ \boldsymbol{ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: 13}\end{array}}}$
