Although there are differences in memory ability, it mainly depends on training. According to psychologists' experiments, learning always forgets, especially mathematical formulas and concepts. If you don't review them in time, you will soon forget them. Therefore, the newly learned mathematical formulas and concepts must be reviewed on the same day, and then reviewed every other day and week until they are memorized.
To memorize mathematical formulas and concepts, pay attention to memory methods. The method is good, it can help to remember and it is not easy to forget. There are many ways to memorize mathematical formulas and concepts. Here are some common memory methods.
(1) formula memory method. Summarize mathematical formulas and concepts into a concise and fluent language, which is easy to read, remember and master. For example, the trapezoid area formula s=(a+b)×h÷2, that is, the upper and lower bottoms of the trapezoid, multiplied by their height, and then divided by 2. If you weave a formula: "Upper bottom plus lower bottom, area times height, don't forget to divide by 2." Then this formula can be firmly remembered.
(2) Image memory method. Through imagination and association, it is helpful to associate mathematical formulas and concepts with what you are familiar with. For example, π = 3. 14 15926 ... In ancient times, someone read "3. 14 159" as "a pot of wine in a temple in the mountains" and immediately remembered it. Another example is the multiplication and division method (A+B) × C = A× C+B× C. Some people think that when two people meet good friends, they should shake hands once when they meet, otherwise it is impolite. So (a+b)×c, a×c and b×c, and then add up their products. If you think so, you won't remember wrong.
There are many examples like the above, and students should summarize them in their studies.
