No matter what the method is, it is ultimately up to the students themselves. Recommend a book: Mastering Mathematical Thinking Junior Middle School Edition, a reference book for junior middle school mathematics and physics, suitable for junior middle school students of all grades and levels.

Read intensively, don't ask people easily, only ask teachers or classmates if you really can't think of it. Persevere, and you will become a master of mathematics!

The micro store has just been launched, and Taobao is expected to be launched this afternoon.
