999×111+333×667=333×(3×111)+333×667=333×333+333×667=333×(333+667)=333×1000=333000
333*666+778*999=333×3×222+999×778=999×(222+778)=999×1000=999000
333×334+999×222,=333×334+333×3×22,=333×(334+3×222),=333×(334+666),=333×1000,=333000.
999×222+333×334=333×3×222+333×334=333×666+333×334=333×(666+334)=333×1000=333000
"999×333=27×(111×111)=27×12321=332667"
999*779+333*666=3*333*779+333*3*222=999*779+999*222=999*(779+222)=999*1001=999000+999=999999我才二年级我都会
能再问:怎么算再答:999*(167+222)再问:感谢你的启发!
332+778+1+999+666=2776
333×666+999×778=333×(3×222)+999×778=999×222+999×778=999×(222+778)=999×1000=999000
666*333+778*999=999*(222+778)=999*1000=999000~雪人
先拆后提取666*333+778*3*333=666*333+2334*333=(666+2334)*333=3000*333=999000
=333×3×111+333×66=333×333+333×66=333×(333+66)=333×399=333×(400-1)=333×400-333×1=133200-333=132867
999×999+1999=999×(1000-1)+1999=999×1000-999+1999=999000+1000=1000000999×222+333×334=333x3x222+333x33
寒樱暖暖为你又遇到这题了=999×778+222×3×333=999×778+222×999=999×(778+333)=999000(或在客户端右上角评价点【满意】)是我前进的动力!你的采纳也会给你
999×778+333×666=999×778+333×3×222=999×778+999×222=999×(778+222)=999×1000=99900020.09×37-200.9×1.9+20
333乘333加999乘889=999x111+999x889=999x(111+889)=999x1000=999000
333000再答:帅哥,求采纳
333*666+999*778=333(666+3*778)=333(666+2334)=333*3000=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*3*111+999*889=999(111+889)=999000
