Do difficult problems in different ways.

Geometry is more about drawing.

Let's talk about tetu first? If it is a triangle, draw an equilateral triangle first.

Spend ordinary pictures again? Then make different auxiliary lines and use different methods, such as 2 * 2 = 4, to represent the addition of two twos.

3*3 is the sum of three 3s, and so on. ......

Is this an analogy? Think about what you haven't learned or what you have learned in connection with what you have learned. ~~?

Remember what you are familiar with, understand what the question type is, what its characteristics are, and why it should be used as a characteristic question! Understanding is not equal to understanding. In the end, it will be inconsistent! When you see a question, you should associate it to see if it is related to what you have learned, and then answer it according to your own understanding and experience! In fact, I simply don't understand and I'm not familiar with knowledge! practice makes perfect

Listen carefully in class, memorize the methods taught by the teacher, and use them flexibly when doing problems.
