2016×20172017-2017×20162016 2016×(2017×10001)-2017×(2016×10001) =0

a=-2016×20172017 =-2016×2017×10001 b=-2017×20162016 =-2017×2016×10001 ∴ a=b

2016×20172017-2017×20162016 =2016×2017×10001-2017×2016×10001 =0

2017

简便运算20162016×2017-2016×2017207 20162016×2017-2016×2017207 =2016*10001*2017-2016*2017*10001 =2017*2016*10001-2017*2016*10001 =0

a=-2016×20172017=-2016×2017×10001, b=-2017×2016×2016=-2017×2016×10001, 所以a=b

2016+20162016+201620162016=2016*(1+10001+100010001) 2017+20172017+201720172017=2017*(1+10001+100010001) 所以原式等于2016/2017

=2018*2017*10001-2017*20172018 =2017*(20182018-20172018) =20170000

1-a=1-20142014/20152015=10001/20152015 1-b=1-20152015/20162016=10001/20162016 1-c=1-20162016/20172017=10001/20172017 因为2015201510001/20172017 所以 a
