The graphics are good, jumping the gun is not.

A reppie? Then she would tear your head off and flail the skin from your bones.

A good reppie like Yoda

Oops!

how do I compute the last three digits of 2014C1+2013C3+2014C5+...+2014C2013 by hand?

Your second term is 2013C3, that can not be right.

Why? It alternates between 2014 and 2013. I will write it out better:

2014C1+2013C3+2014C5+**2013C7**...+2014C2013
