273*99=273*100-273=27300-273=27027

273*99+273 =273*(99+1) =273*100 =27300

这个还要怎么简算啊? 2.73*100=273 附:用简便方法计算 2.73*99 2.73*99 =2.73x(100-1) =2.73x100-2.73x1 =273-2.73 =270.27

=2.73*100-2.73=273-2.73=270.27

273*(99+1)=2730

4.86x99=4.86x(100-1)=4.86x100-4.86x1=481.14

273*99=273x(100-1)=273x100-273x1=27300-273=27027

326*99 =326*(100-1) =326*100-326*1 =32600-326 =32274 你好,本题已解答,如果满意 请点右下角“采纳答案”.

275X99=275X(100-1)=275X100-275X1=27500-275=27225

9.9*273=(10-0.1)*273=10*273-0.1*273=2730-27.3=2702.7
