25hjoerf10 90 * 25 + 10 * 25 = 25 * (90 + 10) = 25 * 100 = 2500
123 * 27 - 23 * 27 = 27 * (123 - 23) = 27 * 100 = 2700
23 * 16 + 16 * 27 = 16 * (23 + 27) = 16 * 50 = 800
40 * 87 - 39 * 87 = 87 * (40 - 39) = 87 * 1 = 87

LaoGao1 1) 90*25+10*25=(90+10)*25=100*25=2500
2) 123*27-23*27=(123-23)*27=100*27=2700
3) 23*16+16*27=(23+27)*16=50*16=800
4) 40*87-39*87=(40-39)*87=1*87=87
