1) 5 × 2 + (37 + 3 × 5) + 37 = 10 + (37 + 15) + 37 = 10 + 52 + 37 = 99
2) (20 + 30 + 14) + 21 + 1 × 2 = 64 + 21 + 2 = 87
3) (31 - 6 - 16) + 14 × 5 + 6 = 9 + 70 + 6 = 85
4) (30 - 11) - 16 + 30 + 17 - 22 = 19 - 16 + 30 + 17 - 22 = 3 + 30 + 17 - 22 = 28
5) (18 - 7) + 20 - 8 + 24 × 1 = 11 + 20 - 8 + 24 = 47
6) 5 + 26 × 2 + (40 × 5 + 14) = 5 + 52 + (200 + 14) = 5 + 52 + 214 = 271
7) 9 × 8 × 10 - (37 + 4) + 2 = 720 - 41 + 2 = 681
8) 29 + 37 + (24 × 3 + 37) + 40 = 29 + 37 + (72 + 37) + 40 = 29 + 37 + 109 + 40 = 215
9) 7 × 1 × (8 × 6) + 14 × 8 = 7 × 48 + 112 = 336 + 112 = 448
10) 4 + (25 × 1 - 25) + 18 + 24 = 4 + (25 - 25) + 18 + 24 = 4 + 0 + 18 + 24 = 46
11) 34 - 10 × 2 + 23 × (4 + 5) = 34 - 20 + 23 × 9 = 14 + 207 = 221
12) 7 × (7 + 12 × 7 + 27 + 28) = 7 × (7 + 84 + 27 + 28) = 7 × (146) = 1022
