How to do math problems well 20, how to do math problems well

Stick it to know that the reward is looking for someone to do it.

The master leads the door and strives to rely on the individual!

1. Adjust your mentality before class, you must not think, hey, it is another math class, and you will be in a bad mood when you listen to the lecture in class, so of course you can't learn well!

2. Be sure to listen carefully in class, and do it to your ears, eyes, and hands! This is very important, you must learn to take notes, if the teacher speaks fast in class, you must calm down and listen, don't memorize, and then organize it in your notebook after class! Stay productive!

3. As the saying goes, interest is the best teacher, when others talk about the most annoying class, you have to tell yourself, I like math!

4. Ensure that every question encountered must be understood and understood, which is very important! Don't ask, don't be embarrassed, learn to draw inferences! In other words, you need to be flexible! You don't need to do a lot of questions, but you need to be fine!

5. There should be a collection of wrong questions, write down the good questions and wrong questions that you usually encounter, and read more and think more, and you can't stumble in the same place!!

In short, don't be afraid of difficulty, don't be afraid of tiredness, and don't be afraid to ask!

Mathematics has always been the most troublesome subject for many students. I feel that no matter how much I study, my grades will always not improve, and I will fluctuate. But he refuses to give up his determination to learn mathematics well, which can really be described as "mathematics abuses me 3,000 times, and I still treat it like my first love." ”

How can I do math problems well? I don't think this question can be answered in a few words. Now, let's talk about some of my learning experiences.

First of all, how to do a good job in math problems, the premise must be to listen carefully and understand the knowledge points thoroughly. When you are in class, you should listen carefully and take good notes. However, we can't just rely on classroom listening, pre-class preview, and some tutorial materials to help us understand and think about a new knowledge point in advance.

Secondly, a summary of the key points as well as a record of study notes. The process of the teacher's teaching is very fast, and there will be a progress in this lesson. Sometimes we may not understand this one question well and miss another question that the teacher is answering.

Therefore, grasp the key points, quickly summarize, record the key places, and ask classmates or teachers in time to answer the things that you don't understand or don't understand in class.

Finally, and most importantly, practice is that. "Just talking and not practicing fake tricks" is only a general absorption of knowledge, but not a good "digestion". Then, the next time this knowledge point appears, you will be unfamiliar and will not be able to do the question.

Ever since junior high school, I've been scared of math, especially functions. At that time, I felt that I had listened carefully in class, but every time I took the exam, I still couldn't answer the questions, or I didn't have any ideas at all. When I saw other students, I could even draw inferences from other students who had not been talked about by the teacher, which was enviable at the time.

Later, I realized that we must not be lazy when learning mathematics, and we must "write more and practice more". Now I still have the "Through" I bought at that time on my bookshelf, recalling the time of "brushing questions", and under the guidance of the famous teacher in the workbook, I slowly made fewer mistakes and improved my grades. In short, for a knowledge point, if you want to do a good math problem, you must usually do a few more questions, memorize a few more question types, practice your feel, and practice your mentality.

Whether it's daily practice or exams, I believe it will be beneficial.

Look at its score for a given time.

Let's take ten minutes as an example.

1) Read the question in 3 minutes.

I'm not talking about staring at it.

I'm sure you know every word.

Don't rush to start thinking about the solution.

Combine the analysis of each condition and write down all the conclusions that can be obtained.

If you have more time, you can combine the conclusions you have reached with the analysis to come to new conclusions (2) and start with it.

Look at the problem, recall the textbook and the topic, and find out the required conditions.

Look for it again from (1).

It can usually be done.

This step takes about 6 minutes.

3) The most important step of this method!

Re-read the question and review the solution process.

Because it uses a conclusion that has been thought out before.

It is possible to use the conclusions reached as conditions directly.

This is the disadvantage of this method.

Review it again, and supplement the unqualified and unproven parts.

I haven't encountered this kind of problem, mathematics has always been my best subject, first of all, you don't reject it, learn and do it seriously, don't know how to ask in time, there is a very important point to summarize, problem-solving ideas and skills, and promote it, maybe you can't do it at the top level, but you will not be troubled by mathematics.

Examination is the key, pay attention to digging the key words, the information given to you, followed by the knowledge pass, the method is simple, and the thinking is clear.

Mathematics is required in college, and in many majors, mathematics is mostly required for graduate studies, so mathematics is still very important.

2.Now that you're in your third year of high school, time is tight, you definitely don't have time to make up for hunger, just do more of the previous real questions, it's really useful, you must think about it yourself when you do it, how to do it, don't can't do it, just look at the answer, even if you spend a little more time, it is more effective.

3.If you have this strength at home, you can also hire a math tutor, of course, the quality of the tutor is still very important, a good tutor can help you in a short period of time. It's not good, don't say that he misunderstands people's children, it always doesn't help much.

4.Arrange time reasonably, combine arts and sciences, review in a planned manner, pay attention to nutrition, and pay attention to rest. It's the best thing to know your body clock and when it's best to remember and when to be logical.

5.Relax your mind, it's easy to go to college now. In the future, there will be a lot of time for you to make up for it in college, and you can learn better in professional courses. If you are too nervous, it will affect the review.

luck！

Seriousness, patience is enough, and you must listen carefully in class.

Thousands of high-rise buildings do not rise from the ground, but need a foundation. First of all, you need to know and understand the meaning of the question, you can start by looking at the relevant example questions, and find a solution to the problem from the example questions.

abcde7

7abcde

Multiply by 5 by the unit of the multiplier, 5 7 = 35, then, e = 5;

Multiply by ten more places e is: 5 5 = 25, add 3 to get d = 8;

Multiply by 100 d, 5 8=40, and add 2 to get c=2;

Multiply the thousand bit c is: 5 2 = 10, and add the carry 4 to get b = 4;

Finally, multiply by 10,000 digits is: 5 4=20, and add 1 digits to get a=1.

So, ABCDE 14285

What about the topic... Let's try the next homework help.

It's too simple to 14285, multiply it one by one.

Solution: There are x rooms, y people.

Because: 3 people per room, 8 more people.

According to this condition: 3x 8 y

Because: 5 people live in each room, then there is a room with less than 5 people according to this condition:

1≤y－5（x－1）≤4

In this formula, 5 (x 1) represents the number of people living in all but the last room, and y 5 (x 1) represents the number of people staying in the last room. 1 y 5 (x 1) 4 means that the number of people in the last room can be 1 or 2 or 3 or 4 people, i.e. "less than 5 people in the last room").

Substituting y 3x 8 into the above inequality.

1≤3x＋8－5（x－1）≤4

i.e. 1 13 2x 4

x from 13 2x 4

By 1 13 2x x 6

Because x is a positive integer.

So x can only be equal to 5 or 6

When x 5, y 23

When x 6, y 26

So there are 5 rooms and 23 people.

Or there are 6 rooms for 26 people.

Question 1(2): = (Explanation: the meaning of empty set), Question 1(3): q r=q (Explanation: q is a rational number, r is a real number, and q is a true subset of r), Question 1(4): z q=z (Explanation: z is an integer, z is a true subset of r), Question 2(1): a b=

Question 2(2): a b=, or writing: a b=, question 2(3): a b=

Is it right to ask a question?

Ask how the negative 2/2 of k came about.

And how did that y-48 come about.

Answer: Bring that coordinate (8,4) into the derivative that is obtained, minus 1 2 oh is y-8, I modified it, you can see the following for yourself Oh is also to lead the way with the (8,4) coordinates, the original analytic formula is to get more 13

A little bit of previous learning experience may help you:

1.Proficiency in knowledge points. That's the basics! And organize the knowledge points!

2.Classify and analyze the problems that may arise from each knowledge point, and refine the corresponding solution ideas!

3.On your own weak points in a certain type, take targeted exercises 4Look at more references and example questions to improve your problem-solving thinking! If you don't have time to do a lot of questions, you can just look at the questions, analyze the solution ideas, and then check the answers to see if your ideas are correct!

5.Perform calculation exercises and improve your number crunching skills!

6.Learn to use problem-solving skills, such as many multiple-choice questions, which do not require calculations, and you can quickly judge the answer through problem-solving skills!

7.The new knowledge points should be studied before the teacher speaks, so that you know it by heart! It's easier to understand if you listen to the lecture again!

8.Be sure to review before the exam and grasp your own knowledge system!

9.Analyze the test papers after the exam, find out where your weaknesses are, and then practice for them!
