999X222十333×334 =333×3X222十333×334 =333X666十333×334 =333×(666+334) =333×1000 =333000.

999换成1000-1.334换成333+1,再合并相加

原式=333x3x222+333x334=333x666+333x334=333x(666+334)=333x1000=333000

方法1 333×(3×222+334’ =333×(666+334) =333×1000 =333000 方法2 999×222+333×334 =(1000-1)×222+333×(1+333) =222000-222+333+333×3×111 =222000+111×(1+999) =222000+111000 =333000

999x222十333x334 =333×3×222+333×334 =333×666+333×334 =333×(666+334) =333000

333x334+999x222 =333x334+333x3x222 =333x334+333x666 =333x(334+666) =333x1000 =333000

999x222+333x334 =333×3×222+333×334 =333×666+333×334 =333×(666+334) =333×1000 =333000

999*222+333*334 =333*3*222+333*334 =333*666+333*334 =333*(666+334) =333*1000 =333000
