Can you help me write almost 100 words with car, forest intention, planning, and contact?

Approximately equal to 5500

According to the rounding rule, a number is accurate to the hundred digit to see the number on the ten digit, the ten digit is 6 is greater than 4, to carry the digit, then this number is about equal to 5500.

Rounding is a method of counting retention with precision that is essentially the same as other methods. However, the peculiarity is that the difference between the retained part and the actual value does not exceed one-half of the last order of magnitude: if the probability of 0 9 occurs, the sum of the errors of this retention method is minimal for a large number of retained data.

That's why we use this method as the basic retention method.

Extended Materials. When using scientific computers for construction calculations, it is common to encounter a situation where to the left of the integer of the answer, sometimes several decimal places are concatenated.

For example, the small side 255 is divided by the large side 1005=.

In this case, if the tan value used as a reference is often used with these decimal points to calculate the size and side of the value, it will be cumbersome. Therefore, in order to properly remove similar decimal points without affecting the accuracy of the actual dimensions, I will introduce the rounding method in mathematics here.

Usually, the carpentry is in contact with the production drawing, are all in the metric system, and in millimeters (mm) as a unit, the area of the production ranges from tens of millimeters to more than ten or twenty meters, as long as it matches the actual size, the decimal point is appropriately deleted, and the error does not exceed one millimeter, the rounding method should be implemented. Where should rounding be applied? In millimeters, if it's in the third place, let's round it to the fourth place, let's look at the fourth place:

If it's 4 or less than four, leave it away;

If it's 5 or 5, round it off as well, but move up 1 to the left of it, this method is called rounding.

In the example above, multiply the tan by the big side to find the small side. Assuming that the tan value remains the same and the large side value is changed to 3000, then in millimeters, it is in the fourth place, and we take the four digits after the decimal point of the tan value as the arithmetic value. The fifth digit is 3, and because it is less than 4, it is rounded off, i.e.

Multiply by 3000 = the decimal point of the answer, at which point less than 1mm, it should be deleted and only 761mm should be taken.

But in rounding, there is a 4 out of 9 chance of rounding off, and 5 out of 9 of 1 rounding up, so the two are different. Therefore, there is a saying of "rounding", in which if it is 5, it needs to be rounded, if the previous digit is an odd number, then it will be rounded in, and if it is an even number, it will be removed.

The car must first understand its structure and working principle, the car has four major components, namely: engine, chassis, body, chassis and including: transmission train, brake system, driving system, steering system, engine is the power system, if you can figure out how they work, you are very powerful, I also learn the car,

Let's learn according to your interests.

My teacher said that now car repair is generally about changing parts, and you can learn whatever you want!

Hello friend bai! To understand the car, you must first understand the car!

1, understand the principle of the car and the structure, DAO is not indispensable! Yes.

Hello friends! To understand the car, you must first understand the car!

1. It is necessary to understand the principle and structure of the car! can allow you:

Engaged in the automotive industry, I usually read more books about automobiles.

Very useful and can be engaged in the industry yourself.

It's very useful, and now when you go out, you usually go out by bicycle, and the effect is quite large.

Now there are more and more cars, and the annual car sales are increasing, but also led to the development of the automotive aftermarket, now in the auto repair society is very short of such talents, so learn the auto repair technology, the future employment does not have to worry.

If you want to learn car knowledge and become a motor car master, then you must find a good master.

Hello, if you want to learn car-related knowledge, you can go to the school to study, professional teachers and equipment allow you to quickly become a master of car understanding, it is recommended that you can come to our school for a field trip.

First go to someone else to be an apprentice, and then there will be a master to take you over time, and you will become a master of bullet trains.

It is best to go to Blue Sky Auto Repair School, which is famous throughout the country and has first-class technology.

Car beauty is relatively simple to learn, but it also needs to be learned carefully in simplicity, and you must pay attention to any detail and must not be sloppy.

If you like to fiddle with machinery and equipment, have a high psychological quality, and learn to drive quickly, you may be able to get a driver's license within a month. If you are not as good as me and learn to drive for three years, I will only get my driver's license in two years and eleven months.

It is not easy to learn, it depends on whether the course design is reasonable and whether the teaching equipment is complete. For beginners, you have to at least understand what it is, what it is for, and then how it works in the context of the system.

Interest is the best teacher, and if you are very fond of cars, I believe it will be easy for you to learn cars.

Of course, it's not simple, the car is made up of thousands of parts, and it is not a simple question to know what role none of the parts play and how to repair them, but to understand and learn carefully.

No line is simple, but if you learn it, it's easy.

In fact, learning automotive technology is very simple, but depending on what major you want to study, different majors may be.

The amount of time and effort it takes to get back to a DAO is different. But if you are willing to put your mind to it, then it's very simple. The teachers of Wuhan Wantong Automobile School teach by hand, and if you don't understand or don't understand, you can consult the teacher, and the teacher will explain the details to you individually.

The library has books on automotive structure, automotive theory, automotive design, automotive engine principle, automotive electronic control technology and other professional knowledge; I also learned some courses related to machinery, what metal materials, mechanics, and drawing! You can also learn to repair after the technician, and you will soon get started.

Personally, it is recommended to learn the automotive new energy major, because the car is popular in the family, almost every household has, there is production and sales, there is sales and after-sales, so the automotive major is still developing, in addition, learning the automotive profession, it is also a technology, relying on their own technology to eat, feed themselves, feed the family is not a problem, at present, new energy vehicles also appear in the domestic market, the development space is indeed very large, gasoline-electric hybrid, you can come to the school to see, field trips, teaching facilities, Faculty, campus environment, etc., I hope you can have a long-term choice!!

If you want to learn beauty decoration, go to Yantai Xinwanyuan, have 18 years of experience, and introduce you to work after graduation.

If you are an apprentice, if the master is your acquaintance, it is better, if you are not an acquaintance, he may not teach seriously, if you don't understand this, you don't understand that, then it will be very laborious to do, and it will take more time to grow slowly. In order to have a better development in the future, it is recommended to find a professional chef training school, so that the system is fully start-up, I heard that many people go to Shanghai high-end car maintenance technology training school to learn, very effective.

Want to learn auto repair·· Don't go to school... There is nothing real technology to learn, it is best to go to the auto repair shop to learn, if you work hard in there to learn for about three years you can be a master, now after the New Year, the auto repair shop is recruiting, but it is best to be introduced by acquaintances, the apprentice in the auto repair shop is normally covered with food and accommodation, 100 fast a month, and so on your technology will slowly add up, the previous year each month at most only about 400 wages, I feel that the auto repair shop is much better than the school to learn, you can really learn technology, And the salary, although tired... This is my personal suggestion, because I am a car parts myself, and I have a lot of friends in auto repair, so you can consider it yourself

There are too many things in this society now, so you should be cautious and careful when choosing.

The most important thing in learning technology is to see if the technology is hot or not, and whether you can find a job after learning it.

Otherwise, it will be a waste of the family's money and their own time, and the gains will outweigh the losses.

When choosing, ask people more often to see how the technology works.

Personally, I think it's good that the auto repair industry is now well-known.
