Question

resolva as expreçoes numericas ?{[18+(4x6):6-(2x2)}+18}=

Answer 1

Olá, Vagne. (=^.^=)/

{[18+(4x6):6-(2x2)]+18} = 36

{[18+(4x6):6-(2x2)]+18} = 
{[18+24:6-(4)]+18} =
{[18+4-4]+18} = 
{[22-4]+18} =
{18+18} = 36

Regras dos sinais: 

+ com + = +
- com - = +
- com + = -
+ com - = -

Elimina:

1) - parênteses ( ).
2) - colchetes [ ].
3) - chaves { }.

 Bons estudos! :-)

Answer 2

Resposta:

{[ 18+ (4×6) : 6- (2×2) ] + 18=

{[18 + ( 24:6-4] + 18}

{[ 18+4-4] + 18}

[18 +0] + 18}

{ 18+18} = 36
