999乘778+333乘666 怎么简便计算？

Answer 1

999X778十333X666
＝999X778十333×3X222
＝999x778十999X222
＝999X（778十222）
＝999X1000
＝999000

Answer 2

999x778+333x666
=999x778+333x3x222
=999x（778+222）
=999x1000
=999000

Answer 3

999*778+333*666
=999*(778+222)
=999*1000=999000

Answer 4

简便计算如下
999×778+333×666
=999×778+333×3×222
=999×778+999×222
=999×(778+222)
=999×1000
=999000

Answer 5

999x778+333x666
=333x3x778+333x666
=333x(3x778+666)
=333x(2334+666)
=333x3000
=999000
