Mathematics is an essential part of human thought and reasoning, and is integral to attempts to understand the world and ourselves. Mathematics provides an effective way to build mental discipline and encourage logical thinking and mental toughness. In addition, mathematical knowledge plays an important role in understanding the contents of other school subjects such as science, social studies, and even music and art.

  Mathematics is applied in various fields and disciplines, i.e. mathematical concepts and procedures are used to solve problems in science, engineering and economics. (For example, understanding complex numbers is a prerequisite for learning many concepts in electronics، The complexity of these problems often requires relatively complex mathematical concepts and procedures when compared to the mathematical literacy mentioned above.

  Since mathematics provides basic knowledge and skills for other subjects, such as science, art, economics, etc., the question of how mathematics intertwines with other subjects is worth addressing. In some curricula, mathematics is offered independently to support the study of other subjects as a 'useful subject', and in others, integrated courses are offered that combine mathematics with other areas.

For the sake of the above, this book was in the science of mathematics in the form of a question and an answer, more than  1500a question and an answer in the science of mathematics for all ages, young and old.
