Question

[ 30 + 2 x ( 5 - 3 ) ] x 2 - 10 =

Answer 1

Resposta:

[30 + 2 x (5 - 3) ] x 2 - 10=58

 [30 + 2 x 2] x 2 - 10=58

  [30 + 4] x 2 - 10=58

     34 x 2 - 10=58

      68 - 10=58

          58

     de outra forma agora

[30 + 2 x (5 - 3) ] x 2 - 10= [30 + 2 x 2] x 2 - 10

[30 + 2 x 2] x 2 - 10=   [30 + 4] x 2 - 10

  [30 + 4] x 2 - 10= 34 x 2 - 10

34 x 2 - 10= 68 - 10

68 - 10=  58

 58
