小知识:两数相乘,一个因数扩大若干倍,另一个因数缩小若干倍,积不变
85.42*7903.29-286.5*790.329+79032.9*4.323
=854.2*790.329-286.5*790.329+790.329*432.3
=790.329*(854.2-286.5+432.3)
=790.329*1000
=790329

85.42*7903.29-286.5*790.329+79032.9*4.323
=85.42*7903.29-286.5*(7903.29*0.1)+(7903.29*10)*4.323
=7903.29*(85.42-286.5*0.1+4.323*10)
=7903.29*(85.42-28.65+43.23)
=7903.29*100
=790329
