This part is dedicated to the so-called *discrete calculus*, sometimes also called the calculus of *finite differences*. This is a subject providing methods for solving difference equations. As opposed to differential equations, difference equations are useful as a mathematical representation for certain physical problems.

The purpose of this part is to develop a calculus of “differences” and a “sums”, in analogy to the calculus of derivatives and Riemann integrals.
