Is math difficult Is math difficult in the end?

It's hot during the summer vacation, what's the good thing about running around, it's better to stay at home and study by yourself.

Mathematics in the second year of junior high school, in my experience, I don't think it's difficult.

How you allocate the time for 2 weeks depends on your first year of junior high school.

You said that your foundation in the first year of junior high school is not good.

Personally, I think it should be taken a week out to consolidate the previous content.

After all, it's not high school, and the pre-study can still be slow, but the original one is not learned first.

It's going to be more troublesome to remedy it in the future

That little brother, I said as a person who came over.

In fact, the knowledge of junior high school is very simple, you don't have to rush to use extracurricular time to watch the first year of junior high school The important thing is to concentrate during class time Follow the teacher's ideas and ask positive questions.

It's okay if you're wrong, it means that you have listened to the teacher's lecture (usually not wrong @@哈哈) It's not difficult to get 2 years old.

Be sure to develop your interest in learning.

You can do it, I'm optimistic about you

Tutoring is very necessary, you can't say wrong with this idea just after the first year of junior high school, but you don't tutor, everyone else is making up, it's best to tutor the knowledge of the first year of junior high school, it's better to preview by yourself, the most effective is to have a small class of 5-10 people in the tutoring class, the money is spent less, and there are more people to listen to the questions asked by others.

I don't know what your textbooks are, but as long as you learn the knowledge of junior high school by heart, there is no mountain that cannot be overcome.

It's not difficult, it's a shortcut to do more questions.

Math requires you to invest a lot of time in doing more problems, so that math will not be difficult over time. Junior high school math is not very difficult, just remember to do more problems. A weak foundation also needs to start from the textbook and understand the most basic so that it can be better used in the future.

Just do more math questions.

That is, you can understand one type of question at a time.

After reading the questions, you will know what to do next.

It is better to read extracurricular books than to read the textbook directly.

First, read the textbook carefully from beginning to end. Let's look at the first year of junior high school. When the time comes to the new class in the second year of junior high school, you must listen to it in class.

I know at least the example problems in the first year of junior high school math textbook. Do the exercises after class by yourself.

The subject of mathematics has always been considered incomprehensible in the eyes of the hungry, but in fact, the difficulty is different for different people. For some people, the math itself is not difficult, while for others it is very difficult to understand. Overall, state math is a relatively abstract subject that requires deep thinking and logical reasoning, which is one of the reasons why it is found difficult to master.

Mathematics as a discipline plays a vital role in modern technology. From the perspective of the development of human civilization, mathematics is one of the important driving forces for scientific and technological progress. Mathematics is not only a subject, but also a method and tool of thought.

Mastering the knowledge of mathematics can not only improve people's logical thinking ability and ability to analyze problems, but also help us understand the world better.

When we start learning mathematics, we need to master some basic concepts and skills, such as mathematical formulas, basic operations, geometric figures, and so on. At this stage, we need to memorize a lot of knowledge points, which is one of the reasons why beginners are most prone to frustration. However, once we begin to understand the nature of mathematics and the way of thinking, we will find that mathematics is not a difficult subject to master.

We reinforce our math skills through practical examples and exercises, just as we build muscles. We need to keep practicing, understanding concepts, mastering methods and skills. In addition, seeking help and explanation from others, as well as referring to excellent math problem-solving textbooks, are also good ways to strengthen your math skills.

Therefore, we cannot give a positive answer to the question of whether mathematics is difficult or not. The difficulty and mastery of mathematics are different for different people, depending on their ability and intrinsic qualities, subject interests and motivation, and the conclusions they come to differently. For some, math is an easy and fun subject, while for others, it is very difficult.

In any case, mathematics has important value for our lives and work. Therefore, we should remain patient in learning and exploring the mysteries of mathematics, so that mathematics can become a powerful tool for us to better understand the world and solve problems. <>

1. Everyone can learn mathematics well.

It is an indisputable fact that mathematics is boring, esoteric, and abstract for many people, but it does not mean that it is difficult to learn. A famous mathematician once said: "To master mathematics is to be good at solving problems, but not entirely in the number of problems solved, but also in the analysis, exploration and deep thinking after solving problems."

That is to say, to solve math problems is not to regard oneself as a problem-solving machine and a slave to solve problems, but to strive to become the master of problem solving, to absorb the methods and ideas of problem solving from problem solving, and to exercise one's own thinking, which is the so-called "math problem to test the candidate's ability". So how to "analyze and explore" and "think deeply" before and after solving the problem? In fact, everything in the world is the same, I wonder if students like Chinese?

If you want to write an excellent essay, you must review the topic, be creative, and have a writing outline, this kind of creativity must be the best in your own life, it is your own personal experience, feeling and thinking, and you will never be able to write a good article by making it up. So to solve a math problem, you must also review the problem, and find out what the problem is known? What is to be desired?

This is called "targeted". "Of" is to open the channel between "known" and "to be sought", that is, "creativity", that is, to use one's existing mathematical knowledge and noisy problem-solving methods to communicate this connection, or to reduce the problem to zero, or to turn the problem into a more familiar problem. This kind of "creativity" is the accumulation of long-term mathematical thinking, the summary of one's own problem-solving experience, and the perception after solving the problem.

Therefore, the summary after solving the problem is the most important that cannot be ignored. I remember that since primary school, our Chinese teacher always asks us to say the main idea of an article after reading it. When we finish a math problem, we also want to summarize its central idea:

What knowledge points are involved in the question; What problem-solving methods or ideas are used in solving the problem, so as to "communicate" with the propositioner, in order to achieve the realm of "comprehension". Of course, the summary after solving the problem should also consider: whether there can be other solutions to the problem; Whether it can be promoted to solve a similar problem.

Only by "drawing inferences from one example" can we really "touch the bypass". In short, we should not be greedy for perfection in any kind of learning, but should strive for excellence.

Because c=90° de is perpendicular to ab and ac is in the old point of brightness, e angle is respectfully ascended cab = angle dae

So the triangle AED is similar to the triangle ABC

And because point d is the midpoint of ab ab bc = 10 bc = 6ad ac = ae ab

ae=ad*ab ac=5*10 8=25 4 (where ac can be obtained from the Pythagorean theorem of repentance and the square difference between ab and bc is 8).

ae = 5 times the root number to the second power (5 times the root number two).

Mathematics is a refinement of concrete things, because it is abstract so difficult, so boring, but if you adapt to its abstract and hidden nature, you will find it very interesting, and you will love it. All natural sciences, as well as some humanities, are inseparable from mathematics.
