High school math learning is confused and confused

Well, according to your situation, it is recommended that you do the following; Preview before class, it is best to use Wang Houxiong's white skin, deeply understand the concept, do the relevant example questions, don't look at the answers, compare with the standard answers after doing it, and do this type of question will always be good in the future; Next, listen carefully in class, understand what you don't understand during the preview, and ask the teacher if you don't understand it yet; To choose a good workbook, you must be thorough, otherwise no matter how many workbooks there are, no matter how much you do the questions, it will be useless; The basic knowledge points should be clearly known in the mind, that is, to build a knowledge network; The above is the preparation. Usually you should train yourself to answer questions quickly and accurately, and perfectly combine the two; You can be excited and a little nervous during the exam, but don't be overly nervous. Now that the exam questions have been placed in front of you, and you can answer them to the best of your ability, reduce the sloppy situation, I want to believe that you also know how much frustration the sloppiness brings to yourself, by the way, you should pay attention to the process of doing the exercises, otherwise it will affect your mentality when answering the questions.

I usually practice a lot, and I don't panic about exams. The exam lasts for two hours, and it is recommended that you finish it within every hour, hoping that your academic performance will continue to improve

In fact, every high school student will encounter such a problem, especially in science, first of all, we must have a calm mind, we must believe that hard work will pay off, and secondly, we must stick to good habits, because mathematics is a process of accumulation. Finally, it is recommended that you summarize frequently, and a good summary can make the effect twice as effective with half the effort. Come on.

If you want to learn mathematics well, the key role is: on the basis of listening carefully in class, you must learn to classify more problems, especially for a class of topics, you must learn to classify, for example, there are several kinds of spherical definition domain problems in functions: (1) greater than or equal to 0 under the root number (2) the denominator is not 0 (3) the true number of the logarithmic function is greater than 0 and the base number is greater than 0 and is not 1

Just these three categories, others want to do this, and it's really impossible to learn it well!!

There are too few questions, and you have to do more in high school math (assuming you're not a math geek). And you have to do it yourself, without looking at the answers. Look at the table of contents of the book and memorize the math book!!

How do you learn math in high school? Is math hard to learn in high school?

Mathematics is a subject, both for liberal arts and science students. It is more important because it is one of the three main courses, and it accounts for a relatively large number of points. If you don't do well in mathematics, you may affect the study of physical chemistry, because those subjects are all about calculations.

However, these calculations are also in mathematics. How do you learn math in high school? What are some good ways to do this?

High School Mathematics. Know the reasons why your child is not good at math:

1. Don't let children learn passively, there are still many students who want to be in junior high school after going to high school, so they follow the teacher's train of thought. I don't have some derivatives, I didn't have a learning method before, and I won't look for it after class. If you practice with practice questions, you just wait for class, and you don't know what the teacher is doing in front of you to write about the content of the teacher's class, and just thinking about taking notes in class is not effective.

2. When the teacher is in class, he should express this knowledge clearly and analyze the key points and difficulties. However, there are still many students who do not pay attention in class. I don't know about many pharmacies, but I take a lot of notes, and there are many problems that I can't understand, and I won't summarize them after class.

Just hurry up and do your homework. When they write their homework, they just mess around and remind them that they don't understand the concepts and rules. Doing questions can only be done by chance.

3. Don't pay attention to the foundation, many children don't have a solid foundation, but they think they have learned well and want to move on to the next lesson, and the premise is that you have to understand all the content of the previous lesson. The evolution of the next question is underway. Find the right way to learn.

For how to learn high school mathematics, it is still important to find a suitable way to learn. The first thing we need to do is to cultivate a good study habit, good study habits include making a study plan, before class, study by yourself, listen carefully to the class when you are in class, and actually consolidate the knowledge engraved after class, and do exercises carefully after class.

At this stage of high school, children say that they are neither small nor big, and at this age, children are very impatient no matter what they do. For this situation, you should not worry. We just need to communicate with the child more and find out the reason why the child is not learning well.

The teacher asks the children to work on the blackboard.

Mathematics is responsible for developing children's arithmetic skills and children's ability to apply knowledge. How to learn math in high school? It still depends on the student's understanding of mathematics.

Students should have their own learning methods, and you should not only grasp the content of the teacher's lesson, but also consolidate and deepen it in time after the class.

Pre-class preview: A commonplace topic, but also a reference to the learning method must be one, although the words are old, although old, but still have to be mentioned. Although everyone understands that this should be done, there are a few people who can really do the pre-class preview, which can make us understand the knowledge to be learned in advance, so that we will not be at a loss in class, deepen our understanding when listening to the class, so that we can quickly absorb new knowledge.

Note-taking: This mainly refers to class notes, because the time for each class is limited, so the teacher will generally be the essence of the things, so it is necessary to record them, one can deepen our understanding, good memory is not as good as a bad pen, and the other can be convenient for us to review and view in the future. If you don't understand what is being taught in class, you should take notes so that you can ponder it until you understand it.

After-class review: Like preview, it is a common topic, but it is also an effective method, dozens of minutes in class are not enough for us to learn and digest what we have learned, we need to do a lot of practice and consolidation outside the class, in order to really master the knowledge learned.

Dabbling in extracurricular exercises: If you want to make achievements in mathematics and get good grades, it is not enough to rely on the knowledge in textbooks, so we need to dabble in more extracurricular exercises, learn their solution ideas and methods, if you really can't understand, you can ask teachers or classmates.

Learn to classify and summarize: learn mathematics to remember a lot of things, especially mathematical formulas, and the knowledge is still very scattered, usually to solve a problem requires the cooperation of various formulas, if you simply memorize each formula, not only increase the amount of memory, but also easy to forget, at this time we must learn to classify and summarize, the formulas that are often used together to memorize, which will greatly reduce our memory, and improve our efficiency (because the formulas are tied together).

In fact, there is a way to solve this problem, which is to establish an error correction book to help us often make mistakes in the questions together (of course, as long as we do it wrong, we can record it), and then look at it when we are free and look at it before the exam, so that the probability of making mistakes in the same kind of questions during the exam is much reduced.

Writing exam summaries: It is a good habit to write exam summaries, which can help us find out the deficiencies in learning and the weak links in our knowledge, so as to make up for the deficiencies in time and the future direction of learning.

Cultivate interest in learning: Interest is the best teacher, only with interest, will be independent and spontaneous learning, learning efficiency will be improved. Of course, it is not easy to establish interest, how to become interested in mathematics still need to be explored by yourself, if you really can't be interested, only to master the above learning methods.

You can buy a copy of Math Gan and take a look.

Listen carefully in class and do more questions.

Questions. Buy in**.

Then memorize the key formula on Xiao Gan.

High school math is simple.

There should be places near high schools where you can buy books.

Questions. Good.

If you really can't do it, it's a few dollars at most.

Questions. Thank you.

At the beginning, I used this thing to memorize it often, and it was very simple to get a college entrance examination of about 140.

This one is also quite convenient, a small book.

You preview before class, listen carefully in class, don't ask the teacher after class, even if he just graduated from college, he will teach you very patiently, I am also a high school student, I can understand your difficulties, don't give up, and do more questions, find the way from the questions, my math teacher said: There is a clever way to learn mathematics, but you have to rely on yourself to find out, after all, everyone is different. Well, good luck!!

IQ, which is above average, and I can't understand anything in high school math.

This is a sign that there is something seriously wrong with your learning methods.

Learning is passive, and it can be said that it is still in the state of learning in elementary school.

Of course, this is not necessarily accurate because you don't know your situation specifically.

Mathematics is the art of thinking, and the problem-solving process in mathematics is not important, it is only about the score.

The most important thing is the method of analysis.

High school math is actually very simple, and many of the content can be translated into elementary and junior high school students.

And if you don't understand, it means that you won't turn the current problem into a problem that you have already learned.

Transforming new problems into old ones is a very important way of thinking in mathematics.

You can talk to me in detail about the specific situation.

Oh math tutoring is a problem, you have several years of loopholes, it's not difficult, but it's not hopeless, after all, the knowledge of junior high school is very simple, you can find your junior high school teacher to tutor you, now you can only try, do your best to catch up, of course it's good to catch up, don't regret not catching up, not all people are suitable for learning!

In high school, you can actually understand it if you do more or have the patience to look at it. You can use the queen male.

Teachers are not the problem, the key is to rely on yourself.

Listen carefully in class and prepare for the lesson.

The reason for the low accuracy rate is that there are mistakes in the details, and when I revise the paper, I find that it is so simple. Therefore, the questions should be meticulous, steady, rigorous, and do not make mistakes in the details.

You can finish a test paper in 50 minutes, which shows that your thinking is very agile, and the speed of calculation is also very good, and the problem you reflect is a common problem that many students have.

I recommend:1. Errors in arithmetic - more training, no difficulty, more practice on questions of general difficulty. Improve basic skills.

3。Be aware of constraints in theorems, formulas, concepts, and more. They must be used accurately.

Hope it helps.

I'm not a prawn!! Hehe, after reading your instructions, I think so! You should be good enough in mathematics, but the main reason for not doing well in the test is the problem of mentality!! As long as you have a correct attitude when you do the questions, you won't be sloppy in the exam.

Your mind is solidified.

The fact that x does not exist in p does not mean that p does not exist or is not true, because p is a set, and if the condition for determining the elements of the set is not true, then the set is an empty set, where p is.

So the guy upstairs is right that p is an empty set, and an empty set is a true subset of any non-empty set, so p can deduce q

In other words, an empty set is the smallest set in scope, and without an element, it is natural to launch a larger set, i.e., an arbitrary non-empty set.

1. Since p is an empty set and q is not an empty set, this question can only say that the set p is a subset or a true subset of the set q, and the sufficient and necessary conditions cannot be discussed.

2. What you call a small range and a large range of launch does not refer to a set, but to an interval. There is a difference between a set and an interval, and the biggest difference is that an empty set cannot be represented by an interval. The reason for your problem is that the set p exists, but it cannot be represented by intervals, so there is no problem of scope and non-scope.

Since x does not exist, p is an empty set, and an empty set is a true subset of any non-empty set, and p is a true subset of q.

In words, where x belongs to the empty set, x belongs to {x, x<3}, so his inverse negative proposition is annoying, x does not belong to {x, x is greater than or equal to 3}, and x does not belong to the empty set. It seems paradoxical.

In fact, as far as mathematics itself is concerned, it requires both human perceptual thinking and rational thinking, and it is a very demanding subject. However, if it is only for secondary school learning, that is, for exams, there is still a certain way.

First of all, you should know that mathematics learning is composed of knowledge points, from points and lines, and from lines to surfaces, so that the learning content of the entire mathematics discipline is formed. Therefore, you should first grasp these points in your daily study, and what is accurate is to fully understand its definition and derivation process.

Then, you need to grasp the relationship between this knowledge point and other knowledge points, you might as well list all the knowledge points related to it, analyze the relationship between them one by one, and derive the process in the forward and reverse directions.

Finally, it's time to do the question. Some people are very easy to do the problem, their associative ability is very strong, they can grasp the key to the problem at once, reflect the required knowledge points and related knowledge points, and quickly draw the solution process. If you can't do it, then you might as well take your time step by step, first understand the topic well, understand what is being asked, and what the conditions are given.

Then carefully understand the knowledge points involved and related knowledge points for each question, and recall the relationship between these knowledge points and the topic. Finally, the application of knowledge points in the process of solving problems is analyzed, how and why they are used. When you've gone through the trouble of asking questions and mentioning, the most important thing is that you sort it out.

In fact, we can find that the types of questions for a knowledge point are limited, and you need to sort out what types of questions you have done about a certain knowledge point (or a few knowledge points), what are the key points of the questions, and what are the key points of solving the problems. When you keep tidying up, your thinking will be clear, and your grasp of knowledge points will be very proficient.

In addition to problem-solving skills, psychology is also very important, you have always felt that you are not good at math, you can't, you can't do it well, and you are even afraid of doing problems and making mistakes. This kind of mentality is not necessary, you have to remember that your task is the college entrance examination, not the usual homework, quizzes, or even mid-term and final exams. So every time you get a question wrong or can't do it, don't be afraid, it doesn't matter if you make a mistake a hundred times, as long as you can do it correctly 101 times and later, and ensure that the high school entrance examination is after 100 times. Come on.
