Answer 1

Resposta:

1) 50- [ ( 6 x 8): (12 + 4) ] =

   50 - [ 48 : 16 ] =

   50 - 3 = 47

2) 38 +[ 7 x ( 6 + 3) - (17 x 3)] =

   38 +[ 7 x 3 - 51 ] =

   38 + 21 - 51 =

      59 - 51 = 8

3) 3 x [5+ (42: 3-9)]=

  3 x [ 5 + 14 - 9 ] =

  3 x [ 19 - 9] =

  3 x 10 = 30

4) 120: [ 3 x 15 +(2 7+1)=

   120 : 15 + 28 =

         8 + 28 = 36

5) [16+(2+(5 x 3) - (21:7 +10) =

   [ 16 +2 + 15 - 3 + 10] =

      33 - 3 + 10 =

          30 + 10 = 40

6) ( 6+2 ) x 3 + 5 =​

       8 x 3 +  5 =

         24 + 5 = 29
