5×96+5.7×4+0.7×66的简便算法5×96+5.7×4+0.7×66的简便算法5×96+5.7×4+0.7×66的简便算法5×96+5.7×4+0.7×66=5×96+5×4+0.7×4+0

5×96+5.7×4+0.7×66的简便算法
5×96+5.7×4+0.7×66的简便算法

5×96+5.7×4+0.7×66的简便算法
5×96+5.7×4+0.7×66
=5×96+5×4+0.7×4+0.7×66
=5×(96+4)+0.7×(4+66)
=5×100+0.7×70
=500+49
=549

好模糊的题 41x101=41x100 41x1=4141 4.05-2.8-0.7=4.05-(2.8 0.7)=0.55 12x(4/1 6/1-3/1)=12x4/1 12x6/1-12x3/1=

呵呵
