6 + 16 + 5 = 44 - 5 - 19 = 24 - 1 - 1 = 48 - 22 - 23 = 10 - 3 + 10 = 4 + 30 - 28 = 1 + 23 - 22 = 10 + 16 + 3 = 9 + 23 + 11 = 6 - 4 + 48 = 23 + 18 - 15 = 30 - 26 + 0 = 12 - 1 + 22 = 20 + 22 + 2 = 6 + 21 + 4 = 40 - 11 - 2

7 = 2 + 5 +

8 = 34 - 25 + 10 = 31 - 18 - 4 = 46 - 2

9 + 3 = 39 - 25 + 1 = 2 + 16 - 14 = 24 + 1 - 1 = 45 - 4 - 10 = 26 - 20 + 22 = 7 + 4 - 2 = 6 + 22 + 12 = 3 + 15 - 6 = 13 + 28 + 8 = 10 + 21 - 2 = 37 - 5 - 30 = 31 - 13 + 5 = 12 + 1 + 22 = 12 + 8 + 29 = 28 - 18 - 6 = 2 + 10 + 7 = 47 - 35 + 38 = 8 + 26 + 3 = 31 + 18 - 4 = 24 - 7 + 9 = 7 + 3 + 40 = 48 - 16 - 16 = 41 - 4 - 20 = 5 + 23 + 20 = 25 + 6 + 0 = 32 + 3 - 7 = 16 + 7 + 20 = 29 + 17 + 4 = 16 + 2 + 20 = 23 + 20 - 23 = 20 - 13 + 17 = 12 + 35 - 16 = 49 - 49 + 39 = 24 + 12 + 8 = 19 + 14 - 26 = 5 + 40 - 26 = 19 - 14 + 6 = 24 - 2 - 9 = 9 - 2 + 37 = 8 + 1 + 13 =

47 - 14 + 9 = 4 + 2 + 41 = 11 + 3 + 30 = 44 + 5 - 19 = 35 - 19 - 3 = 1 + 23 + 22 = 13 + 22 + 1 = 28 - 1 - 0 = 10 + 21 + 2 = 25 - 6 - 0 = 20 + 6 - 10 = 30 - 10 + 6 = 20 + 13 + 17 = 3 + 47 - 42 = 2 + 16 + 14 = 37 + 10 - 29 = 48 - 22 + 23 = 48 - 16 + 16 = 20 - 1 - 11 = 49 - 4 - 9 = 17 + 33 - 48 = 48 - 11 - 16 = 20 + 8 + 18 = 43 - 28 + 6 = 5 + 17 + 13 = 41 - 38 + 43 = 35 - 24 + 2 = 16 - 7 + 20 = 6 + 27 + 11 = 19 + 25 - 32 = 31 - 23 - 3 = 8 + 42 - 33 = 4 + 46 - 34 = 18 + 32 - 40 = 45 - 42 + 4 = 10 + 33 - 9 = 3 + 15 + 6 = 14 + 27 + 0 = 15 + 3 + 29 = 24 + 7 + 9 =
