Answer 2

8 x 9 - 7 x 5 - 3 x 4 = 72 - 35 - 12 = 37 - 12 = 25
63 : 7 + 35 : 7 - 2 x 7 = 9 + 5 - 14 = 14 - 14 = 0
92 -7 x 8 + 30 : 3 = 92 - 56 + 10 = 92 - 66 = 26
72 : 9 + 36 : 6 x 4 = 8 + 6 x 4 = 8 + 24 = 32
81 - 8 x 3 + 45 : 5 = 81 - 24 + 9 = 67 + 9 = 76
57 + 28 - 46 = 85 - 46 = 38
72 : 8 + 64 : 8 = 9 + 8 = 17
