$\boxed{\begin{array}{lr}\mathtt{\bf{{\purple{\mathbb{\star EXERC\acute{I}CIO\star}}}}}\end{array}}$

• Vamos lá, baby angel...

$\boxed{\begin{array}{lr}\mathtt{3 \times 4 \times 2 + 8}\end{array}}$

• Multiplique 3 por 4...

$\boxed{\begin{array}{lr}\mathtt{12 \times 2}\end{array}}$

• Agora, 12 por 2...

$\boxed{\begin{array}{lr}\mathtt{24}\end{array}}$

• Obtendo:

$\boxed{\begin{array}{lr}\mathtt{24 + 8}\end{array}}$

• Some...

$\boxed{\begin{array}{lr}\mathtt{32}\end{array}}$
