M.Sc.

The theme of this thesis can be divided into two major aspects. The first is define, classify integral equations and give some methods that solve them numerically and approximately. Some examples are given, and solved numerically to illustrate the given methods. The second aspect of this thesis is to define singular integral equations and to present some methods that solve them. We solved some examples by the presented methods, also we design a flowchart and a computer program in Pascal language for each method .
