Question

–3 + 5 – {2 – [7 (–2 – 1) : (–3) – 2 (–5 – 1) : 6 – 4] + (7 + 3) : (–5) + 4}
Qual o resultado?

Answer 1

Resposta:

Solução:

$\sf \displaystyle -3 + 5 -\{2- [7\cdot (-2- 1) \div (-3) - 2\cdot (-5 - 1) \div 6 - 4] + (7 + 3)\div (-5) + 4\} =$

$\sf \displaystyle -3 + 5 -\{2- [7\cdot (- 3) \div (-3) - 2\cdot (-6) \div 6 - 4] + (7 + 3)\div (-5) + 4\} =$

$\sf \displaystyle -3 + 5 -\{2- [7\cdot (+ 1) - 2\cdot (-6) \div 6 - 4] + (7 + 3)\div (-5) + 4\} =$

$\sf \displaystyle -3 + 5 -\{2- [+7 - 2\cdot (-6) \div 6 - 4] +10 \div (-5) + 4\} =$

$\sf \displaystyle -3 + 5 -\{2- [+7 - 2\cdot (-6) \div 6 - 4] - 2 + 4\} =$

$\sf \displaystyle -3 + 5 -\{2- [+7 + 12 \div 6 - 4] - 2 + 4\} =$

$\sf \displaystyle -3 + 5 -\{2- [+7 + 2 - 4] - 2 + 4\} =$

$\sf \displaystyle -3 + 5 -\{2- [+9 - 4] - 2 + 4\} =$

$\sf \displaystyle -3 + 5 -\{2- [+5] - 2 + 4\} =$

$\sf \displaystyle -3 + 5 -\{ 2- 5 - 2 + 4\} =$

$\sf \displaystyle -3 + 5 -\{ 2-7 + 4\} =$

$\sf \displaystyle -3 + 5 -\{ -5 + 4\} =$

$\sf \displaystyle -3 + 5 -\{ - 1\} =$

$\sf \displaystyle -3 + 5 + 1 =$

$\sf \displaystyle -3 +6 =$

$\sf \displaystyle + 3$
