2015×20162016 16×20152015怎么算

= 2015× (2016×10000 +2016)-2016×(2015×10000+2015) = 2015× 2016×10000 + 2015×2016 - 2016×2015×10000-2016×2015 =0

2015×20162016-2016×20152015 =2015×20162016-2015×20152015-20152015 =2015×(20162016-20152015)-20152015 =2015×10001-20152015 =0

2015×20162016-2016×20152015 =2015×2016×10001-2016×2015×10001 =0

原式 =2015x10001x2016-2016x10001x2015 =2015x10001x(2016-2016) =2015x10001x0 =0 供参考。

20152016×20162015-20152015×20162016 =20152016×20162015-20152015×20162015-20152015 =(20152016-20152015)×20162015-20152015 =20152016-20152015 =1

我确定没打错

20162016 ÷ 20152015 =(2016×10001)÷(2015×10001) =2016÷2015 =2016/2015

设20152016等于X,20162015等于Y 如题:x*y-(x-1)*(y+1)=xy-xy+y-x+1=y+1-x=20162015+1-20152016=20162016-20152016=10000

解:20152015/20162016 =(2015*10001)/(2016*10001) =2015/2016

20152015÷20162016 =(2015×10001)÷(2016×10001) =2015/2016
