8-4.68/4.5X(0.25+0.5)简便算法
8-4.68/4.5X(0.25+0.5)
=8-468/450*(25+50)/100
=8-468/(75*6)*75/100
=8-468/6/100
=8-6*78/6/100
=8-78/100
=(800-78)/100
=722/100
=7.22

501×99 简便算法怎样计算?
原式
=501x(100-1)
=501x100-501x1
=50100-501
=49599
=(500+1)x99
=500x99+1x99
=49500+99
=49599
或者
=（500+1）x（100-1）
=50000-500+100-1
=49 599
