46 + 3 = 40 + 6 + 3 = 40 + 9 = 49
 
463 = 40 + 63 = 40 + (63) = 40 + 3 = 43
 
28 + 30 = 8 + 20 + 30 = 8 + 50 = 58
 
73 + 20 = 3 + 70 + 20 = 3 + 90 = 93
 
9640 = 6 + 9040 = 6 + (9040) = 6 + 50 = 56
 
8720 = 7 + 8020 = 7 + (8020) = 7 + 60 = 67
 
8 + 47 = 127 = 1225 = 105 = 5
 
9 + 68 = 158 = 1553 = 103 = 7
