The principle of deductive arithmetic refers to getting the correct answer by calculating the answer in the college entrance examination. This method can help candidates get answers quickly and accurately in complex math problems and improve their grades. The achievement of deductive arithmetic principle lies not only in its application in examination, but also in its promotion of candidates' thinking ability and mathematical literacy. The following will introduce the results of calculus principle from two aspects: application and thinking ability.

I. Application

Deductive arithmetic principle is a common method to solve problems in college entrance examination, especially for mathematical problems such as polynomials, functions and trigonometric functions. By calculating the answers, the time and complexity of calculation can be reduced, and the efficiency and accuracy of the examination can be improved. At the same time, deductive method and arithmetic principle can also help candidates better understand mathematical problems and problem-solving ideas, and improve their problem-solving ability and level.

Second, thinking ability.

The achievement of deductive arithmetic principle also lies in its promotion of candidates' thinking ability and mathematical literacy. By calculating the answers, candidates need to master certain mathematical knowledge and skills, and at the same time need to have strong logical thinking and analytical skills. In the process of calculating answers, candidates need to constantly adjust their ideas and methods and choose the most appropriate method to solve problems according to the actual situation. This process can help candidates to cultivate mathematical thinking and improve their mathematical literacy, which is of great help to their future study and work.

In a word, deducing arithmetic principle is a common method to solve problems in college entrance examination, which can help candidates get answers quickly and accurately in a short time and improve the efficiency and accuracy of the examination. At the same time, deductive method and arithmetic principle can also help candidates to cultivate mathematical thinking and improve their mathematical literacy, which is of great help to their future study and work. Therefore, it is suggested that candidates should practice the principles of deduction and arithmetic more and master their application and thinking methods when preparing for the college entrance examination mathematics, so as to achieve excellent results in the college entrance examination.
