13 - 8 = 40 + 40 = 77 - 70 = 9 + 4 - 6 =
26 - 20 = 90 - 20 = 13 - 4 = 87 - 7 + 5 =
30 + 8 = 7 + 9 = 12 - 8 = 45 - 5 + 7 =
12 - 7 = 53 - 3 = 13 - 7 = 14 - 6 + 20 =
8 + 8 = 7 + 80 = 75 - 70 = 15 - 2 - 5 =
14 - 9 = 67 - 7 = 40 + 2 = 6 + 6 - 9 =
15 - 7 = 6 + 20 = 60 + 30 = 59 - 50 + 4 =
18 - 9 = 64 - 4 = 30 + 7 = 15 - 8 + 60 =
4 + 13 = 95 - 90 = 87 - 7 = 60 + 3 - 60 =
11 - 6 = 79 - 9 = 48 - 40 = 20 + 50 + 9 =
