6.25*0.16+264*0.0625+5.24*6.25+0.625*20

=6.25*0.16+2.64*6.25+5.24*6.25+6.25*2

=6.25*（0.16+2.64+5.24+2）

=6.25*10.04

=6.25*（10+0.04）

=6.25*10+6.25*0.04

=62.5+0.25

=62.75

原式=6.25*0.16+5.24*6.25+264*0.0625+0.625*20
=6.25*5.4+264*0.0625+0.625*20
=0.625*5.4*10+264*.0625*0.1+.0625*20
=0.625*（54+26.4+20）
=5/8*100.4
=62.75
不知道对不对，好像也挺麻烦的。
