有会的吗
简算999*779+333*666 有会的吗
999*779+333*666
=3*333*779+333*3*222
=999*779+999*222
=999*(779+222)
=999*1001
=999000+999
=999999
我才二年级我都会做,要加油哦!
999*779+333*666
=333*3*779+333*2*222
=999*(779+222)
=999*(1000+1)
=999000+999
=999999
=333*3*779+333*2*222
=999*(779+222)
=999*(1000+1)
=999000+999
=999999
:橘仔宝宝 也是对的
999*779+333*666
=999*(779+222)
=999*1001
=999*(1000+1)
=999000+999*1
=999999
简单
333×666+779×999=(999×1/3)×666+779×999
=999×222+779×999=(779+222)×999=1001×999=(1000+1)×999
=999000+999=999999
999*779+333*666
=3*333*779+333*3*222
=999*779+999*222
=999*(779+222)
=999*1001
=999999
所以等于999999,这是我3年级期中考试的题,早就会了。(绝对没看楼主的回答)
