Indefinite equation refers to a linear equation or a nonlinear equation with more unknowns than equations and unknown coefficients. International disputes involve conflicts and coordination of interests among many countries, ethnic groups and political groups. The complex relationship between these factors can be compared to the relationship between unknowns in indefinite equations. Therefore, the term indefinite equation can vividly describe the characteristics and essence of international disputes.

International disputes can also be derived from other mathematical terms, such as inequality, variable, infinity, set, etc., to describe various elements and characteristics involved in international disputes. However, the term indefinite equation is closer to the essence and essence of international disputes, and has a deeper meaning and symbolic significance.

In international disputes, contradictions and conflicts arise between countries due to political, economic and cultural differences. These conflicts and contradictions can be manifested in various forms, such as military conflicts, trade wars and cultural conflicts. To solve these international disputes, countries need to communicate and consult with each other, find common solutions, and balance and coordinate the interests of all parties.

The benefits of learning mathematics:

1, improve the ability of logical thinking and problem solving

Mathematics is a very logical subject. By studying mathematics, we can improve our logical thinking and problem-solving ability. Logical thinking refers to thinking about problems through reasoning, induction and deduction, while the ability to solve problems refers to solving problems through analyzing problems, finding solutions and drawing conclusions. These abilities are useful not only academically, but also in daily life.

2, it is widely used

Mathematics is a basic tool in natural science, social science and engineering, so it is widely used in various industries and fields. For example, in the economic field, mathematics can be used to analyze data, build models and make predictions. In the computer field, mathematics can be used to study algorithms, encryption, image processing and so on. In the field of engineering, mathematics can be used to study structures, fluids, electromagnetic fields and so on.

3. Cultivate mathematical literacy

Mathematical literacy refers to the cultivation of mathematical knowledge and skills, so that people have the quality and cultivation of mathematics. By studying mathematics, we can improve our mathematical literacy, so as to better understand and master mathematical knowledge and apply it to real life. At the same time, mathematics literacy is also an important personal quality, which can improve a person's self-confidence and competitiveness.
