Simple calculation of 2015 × 2015-2015 / 2014 × 2014 + 2014
The title should be (2015 * 2015-2015) / (2014 * 2014 + 2014)
If so, the molecule = (2014 + 1) (2014 + 1) - (2014 + 1) = (2014 + 1) (2014 + 1-1)
= (2014 + 1) * 2014 = 2014 * 2014 + 2014 = denominator
The result is 1
2015^2-2014*2016 = 1
2015²-（2015-1)(2015+1)
=2015²-(2015²-1)
=1
