Mathematics is a subject that attaches great importance to experience. Generally, fast and accurate methods are terminated by predecessors. And teachers are nothing more than people who have mastered many such methods and will teach us in class. If we don't pay enough attention in class, then we will miss these methods and take many detours. Not worth the candle!

Step 1: Learn to speak: Speak your mind. It is said that thinking methods can be trained to guide students to answer questions completely in concise, accurate and standardized mathematical terms. Students try to summarize and generalize definitions, laws or formulas in their own words, so that perceptual knowledge can be upgraded to rational knowledge.

Step 2: Learn to practice: Strengthen the process of "doing" through practice. Explore new knowledge in practice and solve new problems effectively. Practice more topics, and you will naturally have inspiration for writing.

Step 3: Learn to remember. A lot of mathematical knowledge can't be memorized by rote. It must be memorized on the basis of understanding, so it is not easy to forget. For some confusing concepts, use comparative method to clarify their connections and differences, and use keywords to remember them. When you are about to forget, it is also an effective way to enhance your memory by taking out class notes or classic questions regularly.

Step 4: Learn to see. Follow the teacher to choose a suitable observation point and conduct purposeful observation and examination. In the process of reading, gradually learn to identify and think, enhance observation and stimulate curiosity.
