☘ Este exercício é bem simples, vamos apenas somar, e por fim, subtrair. Simples, não?!
☘ Vamos ao seu exercício "Quanto é +8-6-12+15-3".
[tex]\boxed{\begin{array}{lr}\mathbf{\green{ + 8 - 6 - 12 + 15 - 3}}\end{array}}[/tex]
[tex]\boxed{\begin{array}{lr}\mathbf{\green{23 - 6 - 12 - 3}}\end{array}}[/tex]
- Agora coloque o sinal negativo em evidência na expressão.
[tex]\boxed{\begin{array}{lr}\mathbf{\green{ - (6 + 12 + 3)}}\end{array}}[/tex]
[tex]\boxed{\begin{array}{lr}\mathbf{\green{ - (18 + 3)}}\end{array}} \\ \boxed{\begin{array}{lr}\mathbf{\green{ - 21}}\end{array}}[/tex]
[tex]\boxed{\begin{array}{lr}\mathbf{\green{23 - 21}}\end{array}}[/tex]
[tex]\boxed{\begin{array}{lr}\mathbf{\green{2}}\end{array}}[/tex]
☘ Cálculo completo abaixo:
[tex]\boxed{\begin{array}{lr}\mathbf{\green{8 - 6 - 12 + 15 - 3}} \\ \mathbf{\green{23 - 6 - 12 - 3}} \\ \mathbf{\green{23 - 21}} \\\mathbf{\green{2}} \end{array}}[/tex]
