the express passengers from Hangzhou to Tiantai get on at Jiubao passenger transport center station in Hangzhou. There are 20 departures every day. The departure time is 7:00, 7:50, 8:35, 9:20, 9:55, 10:10, 10:30, 10:50, 11:15, 11:40, 12:40, 13:10, 13:40, 14:00, 14:30, 15:10 16: 10, 16:35, 17:15, 18:00, 79 yuan.
for example, 9 + 6 divides 6 into 1 and 5, because 9 makes up 10 and lacks 1, so 1 should be separated
therefore, 9 + 6 is decomposed into 9 + 1 = 10, and then 10 + 5 = 15,
therefore, it is necessary to keep in mind that "9 to 1", "8 to 2", "7 to 3", "6 to 4", "5 to 5"
the ten breaking method is a kind of calculation method, that is, when the number of bits is not enough to be subtracted, 10 is used to subtract the subtracted number, and the remaining number is added to the number of bits. For example, in 17-9, first divide 17 into 10 and 7, that is, break 10. When the number of bits is not enough to subtract, subtract 10 from 10, and add 1 from 10-9 to the previous 7.
This is a method to calculate the abdication subtraction within 20, that is, divide the subtraction into two numbers, the subtracted number minus the first number should be equal to 10, and then use 10 to subtract the second number to get the final result
for example, 14-7 can be divided into 4 and 3, first 14-4 = 10, then 10-3 = 7
For example, 15-7 can be divided into 5 and 2, first 15-5 = 10, then 10-2 = 8extended data:
the flat ten method is to divide the subtracted number into two numbers, the subtracted number minus the first number should be equal to 10, and then use 10 to subtract the second number to get the final result. That is to say, the ten methods of leveling. Q18-9 =? You can do this: take 18 and subtract 8, leave 10 and subtract 1
The basic principle is to regard 18 as a 10 and an 8, subtract 8 first, and then move 10. 18-9, bit 8 is not enough to subtract 9, so first subtract bit 8, and it becomes a whole 10. At this time, subtract 1 from this 10 (because 9 = 8 + 1), and the answer is 10-1 = 9for example, 9 + 6, divide 6 into 1 and 5, because 9 makes up 10 and lacks 1, so 1 should be separated. Therefore, 9 + 6 is decomposed into 9 + 1 = 10 and then 10 + 5 = 15. Therefore, we should keep in mind "9 want 1", "8 want 2", "7 want 3", "6 want 4" and "5 want 5"
The even ten method is to divide the subtracted number into two numbers. The subtracted number should be equal to 10 after subtracting the first number, and then use 10 to subtract the second number to get the final result. That is to say, the ten methods of leveling
for example, ask 18-9 =? You can do this: take 18 and subtract 8, leave 10 and subtract 1
The basic principle is to regard 18 as a 10 and an 8, subtract 8 first, and then move 10. 18-9, bit 8 is not enough to subtract 9, so first subtract bit 8, and it becomes a whole 10. At this time, subtract 1 from this 10 (because 9 = 8 + 1), and the answer is 10-1 = 9
extended data:
subtraction follows several important patterns. It's anti commutative, which means changing the order changes the sign of the answer. It is not associative, that is, when a subtraction exceeds two numbers, the order of subtraction is important
Subtracting 0 does not change a number. Subtraction also follows predictable rules related to addition and multiplication. All of these rules can be proved, starting with subtraction of integers and generalizing through real numbers and other things. Continue to learn the general binary operations of these patterns in abstract algebra18-9 = 9 the calculation process of flat ten method is as follows:

taking 15-8 = 7 as an example, children are likely to use their fingers or small building blocks to subtract one by one from 15. After subtracting 8, they find that there are still 7 left. This algorithm is the most primitive and basic method, but the most time-consuming. At first, children can be allowed to use this method, because for the first grade children
they need to use some concrete and image things to help them carry out concrete to abstract dection, so many children will use fingers or small building blocks to complete the calculation, which is a normal performance. In the future, as long as we slowly let the children through practice, realize that other methods are more convenient, and the abstract thinking is stronger and stronger, they will naturally give up this algorithm
For example, we need to calculate 15-8 =?, We can use the relationship between addition and subtraction, as long as we know how much 8 plus is equal to 15, and then dece that 15 minus 8 is equal to several. This method is the most time-saving, but also the most difficult. Children should not only be proficient in carry addition within 20, but also have certain reasoning ability and reverse thinking ability For example, 13-5 =? So the first step is to split 13 into 10 and 3. We know that 10-5 equals 5's good friend 5, then 5 plus 3 equals 8. That is to say, if you divide a dozen into ten and a few, the number you get by subtracting a number will be your good friend. For example, 17-9 =? That is, 17 is divided into 10 and 7, 7 plus 9's good friend 1 equals 8 The results showed that: 1? For example, you can divide it into continuous subtraction, 15 minus 5, then minus 3. Why is that so? Because if you ask your child 15-5 =? 26-6= 39-9= 98-8= You'll find that the child can come up with an answer very quicklythat is to say, two numbers with the same bit (commonly known as tail) can be subtracted to calculate, and the tail will be cut off. For example, 26 minus 6 will cut off the tail 6, leaving 20. Then subtract a number from a whole ten, which is also very easy to calculate

there are only five groups of "Cuoshi": 1 + 9, 2 + 8, 3 + 7, 4 + 6, 5 + 5. I teach students to remember them as five new words, while 1 + 9 and 5 + 5 are easier to remember, and the remaining three are not difficult
"breaking ten methods" is to reverse the "gathering ten methods", as long as children understand that more than ten can be divided into 10 and several, 10 minus several, remaining several, more than ten = several“ After mastering the two methods, you can not only calculate quickly, but also ensure no mistakes

In recent years, with the launch of China's quantum communication science satellite and the landing of "Beijing Shanghai trunk line", more and more procts and business opportunities with the label of "quantum" are emerging, which has helped many consumers, Even if it's expensive
search for "quantum" on Taobao, and there are hundreds of "quantum goods": quantum water, quantum necklace, quantum cigarette case, quantum glasses, quantum car film, quantum radiation proof mobile phone sticker, quantum super porcelain energy bowl... After careful search, there are many quantum health care procts, and some even have the concept of "quantum medicine"
an enterprise named "longai quantum" in Shenzhen boasts "nine major operation sectors" such as quantum agriculture, quantum instry, quantum medicine and quantum health care. As long as it consumes 85000 yuan, it can increase the value by 13.5 times, earn about 1.15 million yuan and provide for the aged for free. The police identified it as "pyramid selling of health care procts", which has been investigated and dealt with in many places throughout the country
Guo guangcan, academician of the Chinese Academy of Sciences and director of the Key Laboratory of quantum information of the Chinese Academy of Sciences, said that the so-called quantum water, quantum medicine, quantum fertilizer and so on are terms that deceive the public, and hype the academic field that should be pure. It can be said that all these propaganda are false and have nothing to do with quantum dots
Academician Guo guangcan said: "to judge whether a commodity is quantum depends on whether it uses the coherence and superposition of quantum. If not, it is not quantum."experts pointed out that quantum technology has not been related to daily necessities for the time being. At present, almost all the so-called "quantum + life" procts are deceptive
Pan Jianwei, academician of the Chinese Academy of Sciences and executive vice president of the University of science and technology of China, for example, said that his relatives had a "quantum Pendant" on their chest, believing that it could radiate something every day, which could prevent cancer; Some people say that if you hit nectarines with "quantum wave", the nectarines will be especially good for your health“ Think of the so-called "nano water" hyped by some people in those years, which makes people laugh and cry. "
"the concept of quantum is very popular. When various institutions are waiting in line for investment shares, if you have an asset management plan or financial proct, please invest in a quantum company with a bright future. The threshold is not high, just a few hundred thousand yuan. Please be careful. Investment needs to be careful, don't treat swindlers as quantum A well-known scientist in the quantum field said in the circle of wechat friends
"I'm worried that the concept of quantum communication has been over hyped. This is not a scientific attitude." Pan Jianwei said that on the one hand, people have a sense of worship for concepts, while on the other hand, science popularization is not enough. Some businesses "rub concepts" to deceive people
at present, the research of quantum technology mainly focuses on quantum communication, quantum computing and quantum precision measurement. Experts pointed out that the prospect and application of quantum technology is very good, but it may be several years before it is really applied to people's lives. Don't disturb the market because of these unscientific hype and make this field lose people's support
relying on the transformation of quantum scientific research achievements of universities such as China University of science and technology, China has established a number of quantum information enterprises such as kedadongquantum technology company. Quantum communication has been able to solve the security problem of information transmission. It has broad application prospects in the protection of information integrity, authentication and signature, and is now in the primary stage of marketization. Pan Jianwei said that if chips for quantum key transmission are added to mobile phones in the future, it is not impossible for quantum technology to enter thousands of households
"there are more fake procts. In the future, we will be disgusted with good and bad quantum procts." Zhao Yong, President of KDD, believes that the abuse of quantum concept is negative to the development of the market and instry
experts believe that the market supervision department should strengthen the supervision of this kind of behavior and regulate it by means of rectifying false advertisements. At the same time, we also need to strengthen science popularization, so that the concept of science can be confirmed in the authoritative platform, and play the role of "intellectuals", "Mozi Salon", "eggshell" and other popular science accounts and platforms, so that the concept can not be used by bad businesses. Consumers should also polish their eyes, involving scientific concepts, and obtain information from formal platforms
