3+5+6 = (3×5)(3×6) 1518 then [(3×5)+(3×6)-6]and reverse the number = 27 = 72
3+5+5 = (3×5)(3×5) 1515 then [(3×5)+(3×5)-5]and reverse the number = 25 = 52

3+6+5 = (3×6)(3×5) 1815 then [(3×6)+(3×5)-5]and reverse the number = 28 = 82

7+9+4 = (7×9)(7×4) 6328 then [(7×9)+(7×4)-4]and reverse the number = 87 = 78
So ultimately the final result is
7+5+6 = 354217
3+5+6 = 151872
3+5+5 = 151552
3+6+5 = 181582
7+9+4 = 632878
