b) 50+ 10 ÷ [ 12 - (2 × 5 - 3 )]
c) 17 + [ 24 ÷ (3 + 1) × 8] - 9
d) 76 + [15 ÷ ( 6 ÷ 2 + 2) + 1]

Answer 1

A) 38+ [7+(32: [12-7]
    38+[7+(32:5)
    38+7+6,4
     R: 51,4

B) 50+10: [12-(7)]
    60:[12-7]
    60:5
    R= 12

C) 17+ [24:(4) x 8]-9
     17+[6x8]-9
     17+48-9
      R= 56

D) 76+[15:(3+2)+1]
     76+[15: (5)+1]
     76+[3+1]
     76+4
     R= 80
