Ten ways:

1, get into the habit of previewing. This is a good way for me to study mathematics for many years, because I know what I can't do by learning what the teacher should say first in advance, and I have a focus when I study. Of course, it would be better if you taught yourself completely.

2. Do exercises with the book. Preview is not an end. If you have time, you can do examples and exercises after class and check the preview. If you can explain everything, you can learn it. Even if you can't, you can listen to the teacher again.

3. Do the homework assigned by the teacher and do it carefully. When you do it, you can write the problem-solving process directly next to the topic, such as multiple-choice questions and fill-in-the-blank questions, because there are many blanks to write in the solution. The advantage of this is that the teacher can keep up with the ideas when talking about the topic, and it is not easy to get distracted.

4. sort out the wrong questions. After every exam, there are always many wrong questions. For these questions, don't think that you will do them if you understand them in class. It's easier to see flowers than to embroider. You will know if you can do it yourself. Moreover, we should refer to the wrong questions in the reference book and re-learn the knowledge.

5. Check for lost traps. After doing a lot of exercises, our math scores have improved, but there are still some problems we can't do. We should be good at finding out which types of problems still have blind spots and then break them one by one.

6. Improve your math scores. I may have studied mathematics for a while, but I always fail in my grades. What is the difference? Basic questions or high questions, and then set high requirements for yourself, strive for the basic questions without losing points, and then do some difficult questions.

The top ten skills are:

1, there is a fixed formula for the conversion between Fahrenheit and Celsius.

2. Multiplication of two digits.

3. Multiply 1 1 by any two digits.

4. Decimal number after pi.

5. Quickly calculate the way to multiply the score by an integer.

6. Butterfly decimal addition and subtraction.

Memory of multiplication tables of 7 and 9.

8. Work out 6, 7, 8, 9 in the multiplication table of 99 by hand.

9. Percentage calculation method.

10, two-digit multiplication.
