How can I be happier if I fail a math test?

I said suicide jumping into the river, you definitely won't go, I said next time I came, you said there was no chance, I said I wanted to open a point, and it would naturally go straight to the bridge, You said there was no water, how could the boat get to the bridge, There is no endless road, there is no road ahead.

So what else to say, the exams have passed, what's the use of complaining, the presence is the scene, there is no after, there is a limit between winning and losing? In some aspects you lose, but you win others, next time you pay attention to the point, who can succeed every time, you won't be wrong in doing the question, even if there is, it is rare to meet in old age, people will break their life span compared to people, and there is a sky outside the sky

The one who laughs to the end is the strongest, the experience of failure is a stepping stone to success, learn from the lessons, what is so scary about being young, it's okay to be a little conceited, don't be afraid, self-confidence is the most important, believe that you will succeed in the end, the goddess of fate will occasionally make a joke with you, come on!

I once went to buy lamb skewers, stretched out 4 fingers and said to the boss, "3 lamb skewers".

The boss was blindfolded, "How many?" ”

I held out 3 more fingers and said "4".

Boss "% When I was playing basketball in high school, after A got the ball, he selflessly passed it to B, and B scored an easy goal After a while, B got the ball, A shouted loudly to pass the ball to him, but B threw the ball himself, and A shouted angrily. I was really blinded just now...... dog's eye

Because the grades are too good, it is easy to have a sense of oppression, and I am afraid of what to do if I fall. If you want to think about what are the two math problems in the many exams in your life, there are many opportunities after learning a lesson!!

Just don't think about it, you just think you've done badly. Just don't be pressured.

Start the analysis from the wrong questions: first analyze the knowledge points, and then analyze them in depth to find out the knowledge gaps, and if it is a subjective reason such as carelessness, cultivate your own ability. The error occurred, the reason for the error, and how to fix the error.

Both short-term and long-term matters are involved! It's better to be comprehensive. I don't know what I said, forgive me...

Carelessness.

The calculations are not careful.

Mistakes: Clerical errors.

I don't remember the formula.

Not feeling well.

Sometimes we think of this as carelessness, but it's not always true. On the one hand, you don't really pay attention to solving the problem, you don't summarize it, or you don't look at the problem enough. In addition, if you do few questions and have little experience, you will not make the mistake you made this time next time, but there will be problems in similar or new places.

In general, you are not proficient, when you are at ease, you will not only be able to do the problem, but you will also know that this problem ** can set traps, there are several variants. Do more questions, summarize more, pay more attention, don't do questions for the sake of doing questions, I hope it can help you.

1. Multiple choice questions: (1) Pay attention to the question requirements to choose the correct or incorrect option; (2) Direct choice method: find the most certain answer and choose directly; (3) Exclusion method:

If the exclusion is incorrect, narrow the scope and then judge; 2. Drawing question (1) should be drawn with a pencil, with a ruler and an eraser. 3. Fill in the blanks and experiment questions: while reviewing the meaning of the question, draw a picture on the straw paper to clarify your thoughts, and pay attention to unit conversion and unification when answering.

4. Calculation questions: (1) Pay attention to write the word "solution" first, write the formula clearly, and operate with units 5. After answering the paper, remember to check no matter how simple it is, so as to avoid the regret of not being able to get a score in a simple question.

Do the roll seriously, don't be nervous, drink saliva if you are nervous.

This should be sloppy, don't be too anxious to do the question, check it a few times!

After getting the test paper for the science exam, close your eyes and be silent for 3 seconds, don't rush to solve the question, then look at the question carefully, and then solve the question, if you can't solve it, first draw a circle to skip, but make sure that there is 30 minutes of time to check.

It seems that the study is careful, not as good as the original;

If so, concentrate and be more careful.

to dissolve it.

Reference.

Mathematics must be careful, not rushed! Be flexible.

Students, it doesn't matter if you don't play well in an exam, find your weak links in the state or, and then make up for this bureau to strengthen.

Question 1: If school A originally has x books, then the title of school B is x*5 7, x-650) (x*5 7+650)=3 4

Solve the equation so that x=2450

A: Originally, there were 2,450 books in School A.

Question 2: If the pile of radishes has x kilograms, then the five baskets of the question are x*(1-3 7)=x*4 7, and each box is x*4 (7*5)=x*4 35;

3*x*4/35+15=x*3/7

Solve the equation to get x=175

A: This pile of radishes has 175 kilograms.

Set up school A original book x books.

Then School B originally had 5x 7 books.

So, x-650):(5x 7 +650)=3:4 solves the equation to obtain: x=2450

Therefore, School A originally had 2,450 books.

2, the rest is 4 7, just 5 baskets, so, each basket can hold 4 35 So, the beginning of the 3 baskets plus fifteen kilograms.

That's 12 35 plus 15 kg.

Set the original x kg of radish.

Then 12x 35 +15 = 3x 7

Guess the cavity: Sui Jian shirt x = 175

So, there are 175 kilograms of turnips in this row.

1 Let A have 7x in the original book, then (7x-650) (5x+650)=3 4 After finding x, 7x is the original quantity of A.

2 is set to x, then a basket has (3x 7-15) 3 kg, (3x 7-15) 3 is set to m first, then 5m=4x 7 can be substituted to find x

Just tell you the method of Jian Xiannian Ha The operation is up to you Ha There is also an exam that doesn't mean anything, come on and study, believe in yourself Don't put too much pressure on yourself, if you have questions to study, you can find it If you can help, you can help Hehe.

I'm a sixth-grader now, and I'm about to start a junior high school, and I'm in a hurry. But usually the exams have always been okay, and the class is at the upper middle level. But this time I felt really too much failure, there were two questions that I couldn't do, but the scores were relatively high.

My parents also had a hard time, but I felt like I was really unhappy. This time, I can only score 90 points after deducting the scores of the two questions in the town, and I don't dare to guarantee that all of them are right, many people have done it right, and I am really useless. I heard that if you want to go to the best middle school in the city, you don't have to think about it if you go to the best elementary school in the city, but I really want to go to that school, and I think that being able to go to a good Yulianji junior high school is also paving the way for the future.

Now I don't even think there's any future at all, am I not doing well?

Just ask questions, and say so many polite words!!

1 Let A have 7x book liquid cover then (7x-650) (5x+650)=3 4 After finding x, 7x is the original quantity of A.

2 is set to make a good fuss, x then a basket has (3x 7-15) 3 kg, (3x 7-15) 3 is set to m first, then 5m=4x 7 can be substituted to find out the sock dregs x

Just tell you how.

You should be serious when you do the questions, and you must develop a good habit of being serious.

After the calculation is completed, it is substituted and checked again.

Also, there is no absolute way to overcome mistakes, and if so, how can you get high or low in various exams?

Check (take the number back and count it backwards).

If you have the ability, you can calculate a question in two ways.

It's just a matter of mentality. If you pay too much attention to the test results, you will become very nervous. There are a lot of people, and you don't have to feel anxious.

Before the exam, you can mentally suggest to yourself that I will definitely do it, even if I do it badly, it doesn't matter. If the revision is in place, don't stay in the classroom and read, you can go out for a walk or chat with classmates to relieve the tension. I wish you to adjust your mentality soon!

Don't take the exam too seriously, since you are usually so strong, it proves that you are capable, you must believe that you will not do what others will do, as long as you do your best, sometimes the result is not so important.

Well, as soon as I see your situation, I want to see that it is exactly the same as mine, I usually do this, before the exam, my brain is blank, my hands and feet are cold, I feel like I haven't learned anything, I should relax my mood appropriately, and then don't think about what to do if I don't do well in the exam and so on, calm down, go through what I have learned quietly, close my eyes and let my mind calm down, until the exam starts, it's best not to have some questions with others in Tylen, That will be your brain more chaotic, close your eyes, carefully, empty, slowly, the nervous mood will calm down, and then just rely on your own ability to play, I use this method is my math score has always been the first in our class!!

1、 (x-4)/3-(x^2-16)/24=8(x-4)/24-(x-4)(x+4)/24 =(x-4)(4-x)/24 =-(x-4)^2/24

2. It is equivalent to finding a fan area with a radius of 5 cm and an arc length of 6 cm (arc length = bottom circumference).

S fan = lr 2 = 6 * 5 2 = 15 cardboard area is 15 square centimeters.

（x - 4）/3 - x^2 - 16）/24 = （-x^2 + 8x -16）/24 = -（x - 4）^2/24

The area of the bottom circle is r 2 = 9

The area of the side sector is 1 2 rl = 1 2 5 6 = 15

So the surface area is 24 cm²

Simplify: (x-4) 3-(x-squared-16) 24=8(x-4) 24-(xsquared-16) 24=-(xsquared-8x+16) 24=-(x-4)squared 24

Simplify: (x-4) 3-(x 2-16) 24=[8(x-4)-(x+4)(x-4)] 24=(x-4)(x+12) 24

Solution: The area of cardboard that needs to be cardboard is:==

Mathematical calculations are easy to make mistakes, but calculations are also essential, so we must improve the correctness of calculations, which can be started from the following aspects:

1. Practice more, which can make perfect, and slowly improve the accuracy, which requires a process of accumulation;

2. Usually do the question carefully, concentrate, not half-heartedly, one will be this and that;

3. Cultivating an interest in computing is not to cope, but to learn well.

If you are in junior high school, you can use a calculator.

In primary school, then do more oral arithmetic training, more practice is the key, and the problem solving must be fast, and time to check can improve the score.

Well, look at your information should be a senior high school student, you can write while writing the steps of the big question, you can read silently in your mind while writing, and the similar steps can be written up and down to avoid certain mistakes, always pay attention to the symbols of each step, do the small problem can be done first with a special value method, and then see how much time is used to do it in the regular way. But in the end, it is necessary to practice a lot of post-calculation and summarize the mistakes is the fundamental solution.

Finally, I wish you all the best in the college entrance examination and admission to your ideal university.

Teach you a method that works 100% on premise that must be adhered to.

The first point is to divide the scratch paper into several large grids, and calculate the problem in one cell (advantages: the calculation process steps are clear and easy to check).

The second point is that when calculating division, it must be remembered that it must be reduced to the simplest form and then divided (advantages: reduce a large number of number operations and reduce the error rate).

The third point is to study more excellent methods of problem solving, and adopt a method that is small and simple to solve problems (advantages: reduce the number of calculation steps, save time, and improve efficiency and accuracy).

Stick to it, remember, now you have to improve the accuracy first, and then increase the rate, don't be afraid that you can't finish the answer, the accuracy rate goes up, and then increase the speed, it's easy to do, but on the contrary, it's even more difficult.

Generally speaking, the whole set of questions should be divided into three types: simple, medium and difficult, grasp the simple, do not be sloppy, try to answer the medium one, and the difficult one depends on my level.
