First, pay attention to the lecture in class and review it in time after class.

Accept a new kind of knowledge, mainly in the classroom, so we should pay attention to the learning efficiency in the classroom, find suitable learning methods, follow the teacher's ideas and think positively in the classroom. Review in time after class and ask questions in time if you don't understand.

Second, do more questions and develop good problem-solving habits.

At first, we should focus on the exercises in books, lay a good foundation, and then gradually increase the difficulty, open up ideas and practice various types of problem-solving ideas. For error-prone questions, you should record them and contact them repeatedly.

Third, adjust the mentality and treat the exam correctly.

During the exam, most of the questions are basic questions, and only a few questions are difficult, so we should adjust our mentality, encourage ourselves, think carefully when doing the questions, don't be impetuous, prepare well before the exam, do routine questions, don't speed up the questions in order to catch up with time, and do them in an orderly way.

The importance of mathematics:

1. Mathematics is a subject that studies concepts such as quantity, structure, change and spatial model. By using abstract and logical reasoning, the shape and motion of objects are counted, calculated, measured and observed. Mathematicians have extended these concepts in order to express new conjectures with formulas and establish strictly deduced truths from properly selected axioms and definitions.

2. Mathematical attribute is the measurable attribute of anything, that is, mathematical attribute is the most basic attribute of things. The existence of measurable attributes has nothing to do with parameters, and the result depends on the selection of parameters.

3. Mathematics is a science that studies the quantitative relations and spatial forms in the real world. Simply put, it is the science of studying numbers and shapes. Due to the needs of life and labor, even the most primitive people know simple counting, and it has developed from counting with fingers or objects to counting with numbers.

4. The knowledge and application of basic mathematics will always be an indispensable part of individual and group life.
