Question

Alguem me ajuda?

Resolva a adição.

(10)+(66)+(77)+(99)=​

Answer 1

Calculando, iremos obter: $\boxed{\boxed{\begin{array}{lr}\boldsymbol{252}\end{array}}}$

• Os parênteses são desnecessários, iremos retira-los. E apenas somar...

$\boxed{\boxed{\begin{array}{lr}\boldsymbol{10 + 66 + 77 + 99} \\ \boldsymbol{ \: \: \: \: \: 76 + 77 + 99} \\\boldsymbol{ \: \: \: \: \: \: \: \: \: 153 + 99} \\\boldsymbol{ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:252} \end{array}}}$

• Que tal vermos a outra forma de conta?!

$\boxed{\boxed{\begin{array}{lr}\boldsymbol{ \: \: {}^{2}10 } \\\boldsymbol{ \: \: \: \: 66} \\\boldsymbol{ \: \: \: \: 77} \\\underline{\boldsymbol{ + 99 \: }} \\ \boldsymbol{ \: \: 252}\end{array}}}$
