Answer 2

25 -15 -80 = 10 -80 = -70
26 -6 -64 = 20 -64 = -44
27 + 3 -48 = 30 -48 = -18
28 + 12 -32 = 40 -32 = 8
29 + 21 -16 = 50 -16 = 34
30 + 30 + 0 = 60 + 0 = 60
31 + 39 + 16 = 70 + 16 = 86
32 + 48 + 32 = 80 + 32 = 112
33 + 57 + 48 = 90 + 48 = 138
34 + 66 + 64 = 100 + 64 = 164
35 + 75 + 80 = 110 + 80 = 190
36 + 84 + 96 = 120 + 96 = 216
37 + 93 + 112 = 130 + 112 = 242
38 + 102 + 128 = 140 + 128 = 268
39 + 111 + 144 = 150 + 144 = 294
40 -30 -140 = 10 -140 = -130
41 -21 -124 = 20 -124 = -104
42 -12 -108 = 30 -108 = -78
43 -3 -92 = 40 -92 = -52
44 + 6 -76 = 50 -76 = -26

Answer 3

1+2+3+4+5+6+7+8+9+10=55

Answer 4

12+1212=5

Answer 5

11*5=55
