Answer 2

O valor da expressão numérica será: $\boxed{\boxed{\begin{array}{lr}\boldsymbol{28}\end{array}}}$

$\overline{\underline{ \: \: \: \: \: \: \: \: \: \: \: \: \:\:\: \: \: \: \: \: \: \: \: \: \begin{Vmatrix}< \heartsuit >\end{Vmatrix} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:}}$

Veja as regras abaixo:

${\tiny{ \mathbf{\rightarrowtail Regra \: de \: eliminac_{\!\!\!,}\tilde{a}o. }}} \\ {\tiny{ \mathbf{\boxed{\boxed{\begin{array}{lr}\boldsymbol{Par\hat{e}nteses > ( \: )} \\\boldsymbol{Colchetes > \begin{bmatrix} \: \: \end{bmatrix}} \\ \boldsymbol{Chaves > \begin{Bmatrix} \: \end{Bmatrix}}\end{array}}}}}} \\ {\tiny{ \mathbf{\rightarrowtail Regra \: de \: operac_{\!\!\!,}\tilde{a}o. }}} \\ {\tiny{ \mathbf{\boxed{\boxed{\begin{array}{lr}\boldsymbol{Potenciac_{\!\!\!,}\tilde{a}o > x {}^{2} } \\ \boldsymbol{Multiplicac_{\!\!\!,}\tilde{a}o \: e \: divis\tilde{a}o > \times/ \div }\\\boldsymbol{Adic_{\!\!\!,}\tilde{a}o \: e \: subtrac_{\!\!\!,}\tilde{a}o > +/ - }\end{array}}}}}} \\ {\tiny{ \mathbf{\rightarrowtail Jogo \: de \: sinais. }}} \\ {\tiny{ \mathbf{\boxed{\boxed{\begin{array}{lr}\boldsymbol{( + ) \times ( + ) = ( + )} \\ \boldsymbol{( - ) \times ( - ) = ( + )} \\ \boldsymbol{( + ) \times ( - ) = ( - )} \\ \boldsymbol{( - ) \times ( + ) = ( - )}\end{array}}}}}}$

$\overline{\underline{ \: \: \: \: \: \: \: \: \: \: \: \: \:\:\: \: \: \: \: \: \: \: \: \: \begin{Vmatrix}< \heartsuit >\end{Vmatrix} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:}}$

• (3×2)×(5-1)+4:

$\boxed{\boxed{\begin{array}{lr}\boldsymbol{(3 \times 2) \times (5 - 1) + 4} \\\boldsymbol{ \: \: \: \: \: \: 6 \times (5 - 1 ) + 4} \\\boldsymbol{ \: \: \: \: \: \: \: \: \: \: \: \: 6 \times 4 + 4} \\\boldsymbol{ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: 24 + 4} \\ \boldsymbol{ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: 28}\end{array}}}$
