Life is a set of relationships in which countless factors interact and go on together. Each of the interacting factors is handled and used as a different discipline when the time comes. Depending on the spirit of the times and the structure of societies, the importance of some discipline areas may change and their place in the agenda may decline. However, this does not apply to mathematics. Because mathematics has served as a constant reference tool for the development of all other scientific fields. Activities that are put forward by ignoring this relationship of mathematics with other disciplines, turn out to be a waste of time and energy. This situation is also valid for educational activities. When mathematics is isolated from other disciplines, ambiguity of meaning and purpose emerges, loses its importance, and becomes a source of concern. The resulting confusion causes mathematics to be perceived as an academic obstacle to be overcome, rather than as a useful tool. It is in the hands of teachers to eliminate this perception and to teach mathematics as the common language of all disciplines. To achieve this, understanding must be changed, and mathematics must be taught based on an interdisciplinary approach.
