1. bitcoin is a kind of digital cryptocurrency. Its inventor is Nakamoto
in essence, we can regard the whole bitcoin system as a super complex mathematical system on the network, in which 21 million complex mathematical problems are limited. We can use the computer as a tool to solve problems, and under the system setting, whoever solves a problem first can get some bitcoin as a reward. If we simply understand it, bitcoin has the same attribute as the well-known q-coin, but there is no upper limit on the number of q-coins. The total number of bitcoins is only 21 million, and many of them have not been g up
in this way, bitcoin seems to be a series of special digital codes obtained by algorithms. It is virtual and has no real value. How can it be used as money
in fact, the currency we use in our daily life is worthless. The money in your pocket is just a pile of light "pieces of paper". The reason why we are willing to accept these "pieces of paper" and think that they are valuable and can be used for trading is because we know that others will also accept these "pieces of paper"
so in fact, as long as something is collectively recognized, even if it is a shell, a stone, or even a brick, it can also be used as a medium of transaction - that is, currency, and bitcoin is no exception.

2. Both of them are equally important. If you have strong spatial thinking ability and calculation error, no matter how strong your thinking ability is, it is equal to 0. If you have calculation ability, but you can't think out problems, it is also equal to O. if you want to learn well, you must have both of them. I hope it will help you

4. It's not a commodity. It's a kind of currency. virtual currency is the same as q-coin, but it's not recognized by national laws. If you are interested in this aspect, you can go to play coin.com. It's all interested in virtual currency

For those pupils with poor grades, it is very difficult to learn primary school mathematics. In fact, primary school mathematics belongs to the basic knowledge, and it is relatively easy to master certain skills. In primary school, it is a period that needs to develop good habits. It is important to pay attention to the cultivation of children's habits and learning ability. What skills do primary school mathematics have
It can be seen from this that the skill of primary school mathematics is to do more exercises and master basic knowledge. In addition, it is mentality. If you can't be timid before the exam, it's very important to adjust your mentality. Therefore, you can follow these skills to improve your ability and make yourself enter the ocean of mathematics6. The most direct. Thinking~
7. Methods to cultivate mathematical calculation ability:
1. Strengthen the training of oral calculation to lay a good foundation for other calculations
mental arithmetic is the basis of all calculations. Only when the basic mental arithmetic reaches a very proficient level can the students have a good calculation level and form a good calculation ability. Therefore, I always use small spare time such as morning self-study to make a one page mental arithmetic card. Parents can also insist that their children do mental arithmetic every day. The content of oral arithmetic includes the oral arithmetic problems in this book and the basic contents of oral arithmetic that have been learned before. Students are asked to practice repeatedly in order to achieve proficiency
Second, design various forms of exercises to improve students' interest in learning calculation
in order to cultivate and improve students' computing ability, we must achieve the goal through continuous and large amount of practice. If we let students do a lot of monotonous calculation exercises repeatedly, students are easy to get tired and can't get the expected effect. Therefore, we must design a variety of forms, flexible, both targeted, knowledge, and interesting exercises, use the students "active", "competitive" psychology, design some mathematical game calculation problems, stimulate students' interest in learning, promote each student to actively participate, in order to get twice the result with half the effort< Third, cultivate students' good calculation habits
1. Cultivate the habit of serious examination. When examining a question, we should do the following: one look (see clearly the numbers and symbols in the question), two strokes (mark out which step to calculate first and which step to calculate later on the question), three thoughts (when to use oral calculation, when to use written calculation and whether to use simple calculation) and four calculations (carefully use written calculation)
2. Cultivate the habit of serious calculation. Train students to be patient, not impatient, think seriously, and be cautious even when doing simple calculation problems. The calculation should be written neatly and the format should be standardized. Even on the draft paper, the calculation should be written clearly to facilitate inspection
3. Cultivate the habit of timely inspection. Check carefully and patiently, and check one by one. First, look up the number symbol, second, look up the calculation process. It can be summarized as the calculation habit of "one step, one turn back". In the calculation, one step, one turn back, one check. Check whether the numbers and symbols are copied correctly, whether the number is accurate, etc., and ask the students to calculate patiently and carefully according to various corresponding calculation rules, so as to overcome the carelessness
4. Cultivate the habit of skillful estimation. The first is to estimate the range of the number before the system calculation; The second is to estimate after system calculation, which can judge whether the number is correct and reasonable.

8. There are four ways to improve the accuracy of mathematics calculation in senior high school entrance examination:
first, we should pay enough attention to calculation
many students always think that computational problems are much easier than analytical problems, and they have a solid knowledge of some rules and laws, so it's easy to calculate. Therefore, they are overconfident or unable to concentrate in calculation, resulting in many mistakes. In fact, it is not easy to calculate correctly. For example, calculate an image 37 × 54 such a simple formula problem, to use multiplication, addition algorithm, after four times table multiplication and four times one digit addition to complete. As for the calculation of a fraction, decimal four mixed operation problem, need to use a lot of knowledge, such as operation order, operation law and four operation rules, after dozens of basic calculation. In this complicated process, the slightest carelessness will make the whole calculation wrong. Therefore, the calculation should not be sloppy
secondly, the calculation should be carried out in the general order
first of all, make clear the meaning of the question and see if there are any special requirements such as simple methods and how many decimal places can be reserved for the number obtained; Secondly, observe the characteristics of the topic to see if there is a simple algorithm; Thirdly, the order of operation is determined. On this basis, the relevant rules and laws are used for calculation. Finally, we should check carefully to see if there are mistakes, omissions and miscalculations
thirdly, we should form a good habit of serious calculation
some students make mistakes because they are not careful in calculation. The data is not clear and the identification is wrong. When making a draft, you can't arrange the vertical type in a certain order, so it's not easy to check and read the wrong data. Therefore, we must develop a good habit of orderly arrangement and careful writing of numbers< Fourth, we should not blindly pursue high speed
correct and fast calculation is the most ideal goal, but we must know that correct calculation is the prerequisite and the most basic requirement, and high speed without correct foundation is of no value. Therefore, we would rather slow down the calculation, but also ensure that the calculation is correct and improve the accuracy of the calculation.
