41x99的简便计算

41X99=41X(100-1)=4100-41=4059

41*99=41*(100-1)=41*100-41*1=4100-41=4059

41乘99简便计算 解:根据题意列式为:41x99=41x(100-1)=41x100-41x1=4100-41=4059

41*99=41x(100-1)=41x100-41x1=4100-41=4059

401*99=401*(100-1) =401*100-401*1 =40100-401 =39699

41x99+41=41x(99+1)=41x100=4100

101x099=10.1*(1-0.01)=10.1-0.101=9.999

41+41x99=41x(99+1)=41x100=4100

41*99+41=41*(99+1)=41*100=4100

41*99+58*99+99=99*(41+58+1)=99*100=9900
