333乘以888÷999的巧算是怎么样?

333乘888除以999巧算:如下 解:333×888÷999 =333÷999×888 =333÷(3×333)×888 =333÷333÷3×888 =888/3 =296 谢谢“codomo126”的提醒

873x999 =873×1000-873×1 =873000-873 =872127

2019÷999 =(1998+21)÷999 =1998÷999+21÷999 =2+21/999 =2又21/999

333x888/999 =888/999x333 =888/(999/333) =888/3 =296 答案是否满意?如果满意请点赞哦!谢谢!

999×778+666×333 =999×778+222×3×333 =999×778+222×999 =999×(778+222) =999×1000 =999000

666*888/999 =2*333*888/(3*333) =2*296*3/3 =2*296 =592

33²-32×34 =33²-(33-1)×(33+1) =33²-33²+1 =1 333×666+778×999 =999×222+778×999 =999×(222+778) =999×1000 =999000 48×22 =50×22-2×22 =1100-44 =1056

999×778十666×333 =999×778十222×3×333 =999×778+222×999 =999×(778+222) =999×1000 =999000

333x666换成999x222,然后 999x(778+222) =999x1000 =999000

999×22+333×34 =333×66+333×34 =333×(66+34) =333×100 =33300
