9.76*0.72-0.72*0.72+0.72怎么简便计算啊
9.76*0.72-0.72*0.72+0.72怎么简便计算啊
9.76*0.72-0.72*0.72+0.72怎么简便计算啊
9.76*0.72-0.72*0.72+0.72
=(9.76-0.72+1)*0.72
=10.04*0.72
=(10+0.04)*0.72
=10*0.72+0.04*0.72
=7.2+0.0288
=7.2288
把0.72提出来，变成（9.76-0.72+1）*0.72=10.02*0.72=7.2144
(9.76-0.72+1)*0.72
9.76*0.72-0.72*0.72+0.72=0.72*（9.76-0.72+1)=0.72*10+0.72*0.04=7.2288
