Rewriting systems (RS), have been widely used in contexts in which formulae manipulation plays a prominent role, such as symbolic and functional programming, formal grammars,computer graphics, simulation, etc. This is due to their intrinsic ability to specify, through employing a set of directed transformational equations, the basic mechanism of subterm substitution.

RS are determined by a series of productions meant to be applied to specific objects. This application consists in the substitution of a pattern occurring on the object also appearing on the left side of a production, by the corresponding pattern on the right side of this production.

The aim of this work is to illustrate the application of RS on a variety of important settings throughout the following themes: One-dimensional Checkers, Group Theory, Equivalence Relations, Systems of Numeric Productions, Recursive Productions, L systems, From Binary Numbers to Compositions and Huffman Coding. A series of animations supplementing several parts of the text is also provided. We are using Mathematica version 5.
