Our main tool will be a discrete analogue of calculus. It offers a difference operator that is a discrete version of the derivative and an antidifference operator that is a discrete version of the indefinite integral. The approach is to take a sum and use the antidifference operator to turn it into a telescoping sum. We begin by illustrating this approach using a simple example.
