Take more time, first of all, to write a clear expression. For example, Abstract cannot be understadable, if not at all. Almost every line includes incorrect expressions. Example given in subsection 4.4 is not specifically meaningful. The paper is something like a text book for undergraduate and example is like a excesise in the text book, at best.
