333乘333加999乘889简便计算

333x333+999x889=999x111+999x889=999x(111+889)=999x1000=999000

333*333+999*889
=333*3*111+999*889
=999*111+999*889
=999*(111+889)
=999*1000
=999000

333×333+999×889
=333×[333+3×889]
=333×[3×﹙111+889﹚]
=333×[3×1000]
=333×3000
=999000

333乘333加999乘889
=999x111+999x889(333分成3x111,把3乘上前面的333=999)
=999x(111+889)
=999x1000
=999000

333乘333加999乘889
=999x111+999x889
=999x(111+889)
=999x1000
=999000
