Is it difficult to learn math in the first year of junior high school, please 3Q for everyone

It's not difficult to adjust your mentality before class, you must not think, hey, it's a math class again, and you're 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! You can ask this question here, which shows that you really want to learn math well!

Mathematics in the first year of junior high school is not difficult, in fact, every mathematics book is divided into several sections, namely: real numbers, geometry, functions and comprehensive application problems, etc., the most difficult of which is function, always placed in the last question of the high school entrance examination, I hope you can learn well when studying!

It's not difficult, just do more questions Geometry is better to draw more, or cut turnips.

Junior high school math is not difficult.

It's not difficult, it's not difficult if the foundation is good, and it's not so difficult if the foundation is not good.

It's not difficult, just prepare for it.

It's not difficult, as long as you master the method, you'll be fine.

Mathematics is not difficult in the first year of junior high school.

Mathematics is not difficult in the first year of junior high school. As long as the child's mathematics foundation in primary school is laid, the mentality of learning this subject is good, and then follow the pace of the teacher's leadership, because the teacher will slowly lead the child to do a good job in the connection of junior primary school knowledge. The most important of these are:

If you don't understand, you must ask the teacher or classmates, you must understand, don't have an ambiguous attitude, and understand Liang Xiang if you don't know it, this subject is not difficult.

Expand your knowledge:

During this period, if parents help their children develop the following abilities, it is very important for future learning.

The first is computing power. Compared with the simple addition and subtraction of positive numbers, the difficulty of mathematics has been significantly improved compared with the introduction of negative numbers and algebra, and errors are more difficult to find. If you have a good foundation in the first year of calculation, you will also benefit from the subsequent deeper calculations such as inequalities, fractional probability statistics, equations and functions.

The second is to establish a preliminary functional thinking. One of the difficulties in the first semester of the first semester of junior high school is the moving point, which generally appears in the form of classification discussion, and its essence is the concrete expression of the functional relation, and this part of the students with insufficient thinking ability is also difficult to understand the core of the function, that is, the change in the relationship between numbers.

If the movement of simple moving points, equations, functions, and more difficult geometric figures can describe a unified thinking system, it is not only beneficial to the learning of functions in junior high school, but also the core foundation of functions in senior one.

The third is the ability to prove reasoning geometrically. The geometric content of the first year of contact is relatively basic, including three views, the sum of the inner angle and the outer angle of the reburial, and the parallel line theorem.

This part of the question type practice is recommended to be improved, and the geometric reasoning ability can be exercised beyond the outline, otherwise the child will have higher requirements for thinking ability in the first semester of the second semester of junior high school, and the difficulty will rise greatly, and it is easy to fail to keep up.

Mathematics is not difficult in the first year of junior high school.

mathematics [English: mathematics, from the ancient Greek máthēma); Often abbreviated as math or maths], it is a discipline that studies concepts such as quantity, structure, change, space, and information.

Mathematics is a general means for human beings to strictly describe and deduce the abstract structure and pattern of things, which can be applied to any problem in the real world, and all mathematical objects are artificially defined in nature.

In this sense, mathematics is a formal science, while Silo is not a natural science. Different mathematicians and philosophers have a range of opinions on the exact scope and definition of mathematics.

In the historical development of human beings and social life, mathematics plays an irreplaceable role, and it is also an indispensable basic tool for learning and researching modern science and technology.

Mathematics originated in the early production activities of human beings, and the ancient Babylonians had accumulated a certain amount of mathematical knowledge since ancient times and could apply practical problems. From the perspective of mathematics itself, their mathematical knowledge is only obtained through observation and experience, and there is no comprehensive conclusion and proof of Huilu code, but it is also necessary to fully affirm their contributions to mathematics.

The knowledge and application of basic mathematics is an integral part of individual and group life. The refinement of its basic concepts can be seen in ancient mathematical texts in ancient Egypt, Mesopotamia, and ancient India. Since then, there has been a steady stream of development.

But algebra and geometry at that time remained independent for a long time.

Algebra is arguably the most widely accepted form of "mathematics". It can be said that since everyone started learning to count when they were young, the first mathematics they came into contact with was algebra. As a discipline that studies "numbers", algebra is also one of the most important components of mathematics.

Geometry was the first branch of mathematics to be studied.

It is necessary to arrange two baskets with x flat poles.

2x+57-x=108

x=5157-x=6

So there must be 51 + 6 2 = 63 (people).

Solution: If x people are carried with a flat pole, then 57-x 2 people will pick.

x/2+2(57-x/2)=108

Solution: x=12

So there are 12 + 51 = 63 people.

A: 1353 1353 1353...

B: 135531 135531...

In fact, A repeats four beats and B repeats six beats.

Therefore, A 200 beats = 4 * 50, just hit the note of 3;

And B 200 beats = 6 * 33 + 2, that is, he also just hit the sound of 3.

So choose B for this question.

The fourth answer, the sound made by the left hammer is a 5-syllable cycle in the unit of "left-center-right-center", 2000 5=400 The remainder is 0, that is, exactly to complete a cycle, so the left hammer falls on the first pipe. Make a "1" sound.

In the same way, the sound produced by the right hammer is a 6-syllable cycle in the unit of "left-center-right-right-center-left", 2000 6=333 and the remainder is 2, so the right hammer falls on the second pipe. Make a "3" sound.

If the machine X is transported from city B to city C, the freight is 300x yuan, and it is necessary to transport (10-x) units from city A to city C, and the freight is 400 (10-x) yuan, then the freight is 500 (6-x) yuan from city B to city D, and the freight is 800 (2+x) yuan.

then 300x+400(10-x)+500(6-x)+800(2+x)=9600

The solution is x=5, so (10-x) = 10-5 = 5 units are transported from city A to C.

Of course, you can also set a to x.

If A to C is to be transported to X units, then B to C is transported to 10-X units.

Total shipping cost y=400x+300(10-x)+800(12-x)+500(6-10+x).

10600-200x

x=5, so A to C transport 5 units.

If A to C is to be transported to X units, then B to C is transported to 10-X units.

Total shipping cost y=400x+300(10-x)+800(12-x)+500(6-10+x).

y =10600-200x

So when y=9600.

9600 =10600-200xx=5

If A to C is to be transported to X units, then B to C is transported to 10-X units.

9600=400x+300（10-x）+800（12-x）+500（6-10+x）

9600=10600-200x

x=5, so A to C transport 5 units.

Landlord,Don't give up the math of the first year of junior high school.,It's actually very easy to learn.,My junior high school math has always been the first in the grade.,In fact, there was no trick at the time.,I'm also very playful.,But I'm never lazy when I do the problem.,Come on.,Do more questions.,Don't pursue too difficult questions if the math is too bad.,As long as you practice more.,The effect must be seen!

It's not difficult, as long as you master the rules.

1. Learning mathematics is the same as learning other courses, pay attention to listening to lectures in class, preview and review in class or after class, and learn each knowledge point thoroughly. But each course has its differences: for example, if I didn't take a Chinese class today, I can make up for it tomorrow after the class, while mathematics is a ring after a link, such as:

If you don't learn decimal addition and subtraction first, you won't be able to, so you must learn each knowledge point thoroughly.

2. Students are most afraid of making mistakes in the exam, and if they make mistakes, they must analyze and summarize. I summarized the four situations in which points are lost: one is that you will do it, but you are careless and do it wrong.

The second is that you can't think of how to do it for a while, and you will do it afterwards. The third is that you don't have enough time, give a little more time to think, and maybe you will do it. The fourth is that you can't do it, you can't do it if you sit there for 10,000 years.

The solution is as follows: First, be careful in the future, and be careful. Second, in the future, we must do more practice, the so-called "familiar with 300 Tang poems, can not compose poems and chant".

Three, be able to use time! Be quick! But it's fast and error-prone!

How can it be fast? There is only one way: practice more!

The fourth is the most terrifying! There are two scenarios for this. One is that you can't do it because you haven't learned it well and can't do it; Another situation is that you have learned well, but you lack the ability to draw inferences and comprehensively, and you can't do it.

Most of the students have the second problem. It makes sense for the teacher to come up with such a question. The teacher will never come up with the questions that everyone will never do, and the teacher is testing everyone's comprehensive ability.

You have to make a few more detours in your brain, think about a few more whys, and you can make it.

Is it difficult for you to think about it.

The math of the first year of junior high school is super easy---
