Answer 1

( 5 +3) +4 = 5 +(3+4)
 8 +4  = 5+7
12    = 12

(12 +8 ) +6 = 12 + (8+6)
20 +6    = 12 +14
26  = 26

( 15 +13 ) +10 = 15 +( 13 +10)
28 +10 = 15 +23
38  = 38

( 25 +11 ) +7 = 25 +(11+7)
36 +7  = 25 +18
43  = 43

(3 +4 ) +5 = 3 + (4 +5)
7 + 5 = 3+9
12  =12

(110 +28) +15 = 110+(28 +15)
138 +15  = 110 +43
153  = 153

( 23 +13 ) +17 = 23 +( 13 +17)
36 +17  = 23 +30
53  = 53

( 48 +12 ) +78 = 48 + (12 +78)
60 +78 = 48 +90
138  = 138

(37 +42 ) +22 = 37 +(42 +22)
79 +22  = 37 +64
101  = 101

(15 +55 ) +5 = 15 + (55+5)
70 +5  = 15 +60
75  = 75
