what are the spaces between the numbers supposed to mean?
letx=20142014
then 20142015=x+1
then 20152014=x+10000
then 20152015=x+10001
20142015×20152014-20142014×20152015
=(x+1)(x+10000)-x(x+10001)
= x²+10001x+10000-x²-10001x
= 10000
then 20142015=x+1
then 20152014=x+10000
then 20152015=x+10001
20142015×20152014-20142014×20152015
=(x+1)(x+10000)-x(x+10001)
= x²+10001x+10000-x²-10001x
= 10000
