对于两个数,A=﹣2016×20170217,B=﹣2017×20162016...

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

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

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
