1) 29*25+15*6+19*15 = 29*25 + 15*(6 + 19) = 29*25 + 15*25 = 25*(29 + 15) = 25*44 = 1100
2) 26*18+26*17+14*35 = 26*(18 + 17) + 14*35 = 26*35 + 14*35 = 35*(26+14) = 35*40 = 1400
1) 29*25+15*6+19*15 = 29*25 + 15*(6 + 19) = 29*25 + 15*25 = 25*(29 + 15) = 25*44 = 1100
2) 26*18+26*17+14*35 = 26*(18 + 17) + 14*35 = 26*35 + 14*35 = 35*(26+14) = 35*40 = 1400
