I always forget when I recite history, and I am very vague when I do problems. I heard that there is a memory method, horizontal and vertical. How did it happen?
It is very important to remember the time by memorizing the history, but in fact, it is very rare to directly test the historical occurrence time in solving problems. It is to link all kinds of historical time together and solve the problem through an event. Therefore, you should analyze the rules and skills of solving problems, remember all kinds of events together, and explore a rule to follow by yourself.
