Mathematics in general is an abstraction. Of course, if it is not an easy subject, but in the same time it is rewarding one. We have to keep in mind that Mathematics is a part of our culture. In developed, developing and underdeveloped countries nobody can count himself truly good educated without Mathematical Concepts. Perhaps one can say that all individuals have to understand in some degree what Mathematics is and what it does. Unfortunately it has always been a great problem in Mathematics, despite the publication of hundreds of Mathematical books, to understand the essential meaning of it. Above all it is a human subject with its own concepts, axioms, postulates etc. [1, 2, 4].
