Mathematics plays a vital role in logical reasoning. First of all, mathematics is a formal language, and its basic element is symbol. These symbols are combined and operated by certain rules to form a strict reasoning system. This formal feature enables mathematics to clearly express complex logical relations and avoid ambiguity and ambiguity in daily language.

Secondly, the logical reasoning method of mathematics plays an important role in cultivating people's logical thinking ability. For example, the process of theorem proving is a process of logical reasoning, and it is necessary to use logical methods such as induction, deduction and disproof, which is helpful to improve people's logical thinking ability and critical thinking ability.

In addition, the logical reasoning method of mathematics is also widely used in other disciplines. For example, in physics, Newton's laws of motion are obtained through logical reasoning; In computer science, the design and analysis of algorithms also need the method of logical reasoning.

Finally, the logical reasoning method of mathematics is also helpful to solve practical problems. For example, in economics, by establishing a mathematical model, we can make logical reasoning about economic phenomena and make predictions and decisions.

Generally speaking, mathematics has played a lot of roles in providing formal language, cultivating logical thinking ability, applying it to other disciplines and solving practical problems.
