Counting in two different ways or giving a bijection between two sets one of which is counted by the LHS and the other is counted by the RHS.

@Steven Stadnicki . I have edited the question now. Finite calculus is analogous to simple calculus just applied on discrete sets. Here we are working with integers. We might be able to derive the equation using it.
