​

Answer 1

Resposta:

$\sf 3 - \{ 2 + ( 11 - 5 ) -[ 5 + ( -3 + 1 )] + 8 \} =$

$\sf 3 - \{ 2 + 6 -[ 5 + ( -2 )] + 8 \} =$

$\sf 3 - \{ 2 + 6 -[ 5 -2] + 8 \} =$

$\sf 3 - \{ 2 + 6 -3 + 8 \} =$

$\sf 3 - \{ 8 -3 + 8 \} =$

$\sf 3 - \{ 5 + 8 \} =$

$\sf 3 -13 =$

$\boldsymbol{ \sf \displaystyle -\: 10 }$
