This book is created to enhance the understanding of Mathematics model in Numeric methodology. It is aimed that the scientist and engineer will be more understanding the behind of calculative methods which applied for their job and also suitable for undergraduate student. This fundamental approached will give clearer picture the basic concept of ma thematic algorithm and emphasize on their simple formulas. It was compared with other advanced numerical book the explanation for the concept is much more complicated and difficult to understand their application formulas. Hence, those whose interested in Mathematical model by using this book they will get a lot of beneficial ideas and will lead them to solve the problem related to complexity of engineering problem.
