4.65×32+2.5×46.5+0.465×430的简便算法谁会？

4.65×32+2.5×46.5+0.465×430
=4.65×32+4.55×25+4.65×43
=4.65×(32+25+43)
=4.65×100
=465
用的是小数运算 可以把小数点跟换 在最后 加上 更简单

很简单啊
原式=4.65×32+25×4.65+4.65×43
=4.65×（32+25+43）
=4.65×100
=465

4.65×32+2.5×46.5+0.465×430
=4.65×32+4.55×25+4.65×43
=4.65×(32+25+43)
=4.65×100
=465

4.65*32+25*4.65+4.65*43
=4.65*(32+25+43)
=4.65*101
=469.65

是不是 4.65*32+2.5*10*46.5/10+0.465*10*430/10=4.65*32+25*4.65+4.65*43=4.65*（32+25+43）=4.65*100=465 你看看对不
