The following are some common types and methods of quick and clever calculations in primary school Mathematical Olympiad: ** 1. Clever calculations in addition ** 1. ** Rounding Method ** - When adding several numbers, if there were two numbers that could be added together to get a whole ten, a whole hundred, a whole thousand, etc., they could be added first. For example, 24 + 44+56, because 44 + 56 = 100 is a whole hundred, so first calculate 44+56, then add 24, that is, 24+(44 + 56)=24 + 100 = 124. - For an equation like 53+36 + 47, because 53+47 = 100 was a whole hundred,+47 could be moved with the sign to the front of +36, and then (53+47)+36 = 100+36 = 136. 2. ** Split and Rounder Method ** - In the case of 96+15, 15 was split into 15 = 4+11, because 96+4 = 100, which could be rounded up first, that is, 96+15 = 96+(4+11)=(96 + 4)+11 = 100+11 = 111. - For 52+69, since 69+31 = 100, 52 was split into the sum of 21 and 31, and then 31+69 = 100 was rounded up, which was 52+69=(21+31)+69 = 21+(31+69)=21 + 100 = 121. - When calculating 63+18+19, 63 was split into 63 = 60+2+1. Because 2+18 and 1+19 could be rounded up, 63+18+19 = 60+2+1+18+19 = 60+(2+18)+(1+19)=60+20+20 = 100. 3. ** The clever calculation of adding the same number ** - For 28+28+28, you can think of it this way, because 28+2 = 30 can be rounded up, but in the end, you have to subtract the three additional 2s, that is, 28+28+28=(28 + 2)+(28 + 2)+(28+2)-6 = 30+30+30 - 6 = 90 - 6 = 84. ** 2. Clever calculation in the substitution (position swap method)** - In an algorithm, the position of the numbers could be changed, and the order of the calculation of the numbers could be changed. For example, 632 - 156 - 232 = 632 - 232 - 156 = 400 - 156 = 244. ** 3. Clever calculations in multiplication ** 1. **"Tongbu" and "Butong" Quick Calculation Method ** - If the sum of two numbers was equal to 10, then the two numbers were complementary. In the integral multiplication operation, for example, 72×78, where the ten digits of the multiplication and the multiplication were the same, and the single digits were complementary (this kind of formula was called "same head, complementary tail" type), and 26×86, where the ten digits of the multiplication and the multiplication were complementary, and the single digits were the same (this kind of formula was called "complementary head, same tail" type), there were very simple and direct fast calculation methods. They were called the "same-complementing" fast calculation method and the "complementing the same" fast calculation method. ** 4. Other methods ** 1. ** Borrowing Method ** - Borrowing a number from a number, turning it into a whole ten or a whole hundred or a whole thousand, and finally, deducting the borrowed number. For example, 9+99 +999+9999=(10 - 1)+(100 - 1)+(1000 - 1)+(10000 - 1)=10+100 + 1000 + 10000 - 4 = 11106. 2. ** Choose a reference number ** - Among all the numbers, find that everyone is close to this number (this number is the benchmark number), first multiply the number of numbers by this benchmark number, and finally, subtract the excess. For example, 489+487+483+485+484+486+488. First find the base number 490 among these numbers, then use 490×7. Finally, subtract the excess, which is 490×7 - 1 - 3 - 7 - 5 - 6 - 4 - 2 = 3430 - 28 = 3402. Read more exciting novels for free
The lyrics of " Glaze " were as follows: Love is like glass, condensing your tears. The more beautiful you look, the easier it is for your heart to break. The new moon has just risen, my heart is far away with you, the road back is too long, birds are born in pairs, why block it. Love is staying together day and night, it is your gentleness; love is waiting year after year, waiting for your return; love is a love curse of life and death, a worry that you don't want to solve; love is repeated endlessly, never asking whether or not. Love is like flowing clouds, the spring breeze does not return ten miles away. It is said that the more drunk you are, the more you want to taste it. The new moon has just risen, my heart is far away with you, the road back is too long, birds are born in pairs, why block it. Love is staying together day and night, it is your gentleness; love is waiting year after year, waiting for your return; love is a love curse of life and death, a worry that you don't want to solve; love is repeated endlessly, never asking whether or not. Love is staying together day and night, it is your gentleness; love is waiting year after year, waiting for your return; love is a love curse of life and death, a worry that you don't want to solve; love is repeated endlessly, never asking whether or not. The moon fell into the clear and silent glaze that we will never meet again in our lives. At this time, the mountain wind, rusty gold, and the sea rain sang an old poem in the clouds. You must burn the endless and abundant love, and all things grow in your eyes. But in this world, you must hold your breath in love. Where do you return to naivety? You must go to a fearless dream in your life. The world despises you or... sprinkle it into the crescent moon spring. The deep affection is overflowing like glaze. Love is fragile. We finally learn to be careful, as quiet as glaze. Love, listen carefully, happiness will echo, every bit of effort will make the memories more crystal clear, not afraid of the baptism of time to continue moving, love is like glass. Also: Exploration, the appearance of heaven and earth, the sword gathers up the sandstorm, the enlightenment of the world of mortals is in the sheath; Ask, the maze, cross the Liao of heaven and earth, and all things are small in the wind; My tears, the clarity of glass, compassion, move the war, calm the earth, the dragon enters the mountains and rivers, don't test me, the enemy is unpardoned; Look at this road, cross grudges, create, Nirvana, turn a few times, through the sorrow and joy of several generations, refine my heart; I am brave, I love, happy and regretless, love for thousands of years, fight the three realms, six realms, nine heavens, swear to follow, drink the water of the River of Forgetfulness, and live up to the meeting; My soul is the core of flesh and blood. All living beings are infatuated with separation and reunion. A single thought is separated by heaven and earth. They taste karma and taste pain. Look at this path. It is to overcome grudges, create, and Nirvana. It turns a few times. It refines my heart through sorrow and joy. I am brave, I love, I am happy and regretless. I have thousands of years of love. I fight the three realms, six realms, and nine heavens. I swear to follow you. I drink the water of the River of Forgetfulness. I will not let you meet again. Bloodline is unbounded by good and evil, Yin and Yang. It is mutually generated and restrained. It is empty. I choose between obsessions. I choose with kindness, not heaven.

In Taoist culture, there were many spells to exorcise ghosts and evil spirits, such as the Golden Light Divine Mantra. The contents of the Canopy Divine Mantra included: "Canopy Canopy, Nine Elemental Evil Child…Devour demons and ghosts, drink the wind…If there are any little ghosts, come and see." The Sky-shaking Axe, the Five Forms of Ghost Slaying…etc. These spells were believed to have the ability to exorcise ghosts. However, the so-called " possession " was a supernatural concept.

The following is an analysis of the window business model of the university cafeteria: ** 1. Initial preparations ** 1. ** Experience accumulation ** - It is best to have university food and beverage business experience, and the time is not less than one year. This was because the university had its own unique cycle. For example, after the new students reported in September, the school was full of people, and the turnover was more guaranteed. In the next semester, the internship of the third and fourth year would cause some students to leave the school and enter the off-season (except for some special windows). Through a year of operation, one could have a comprehensive understanding of the overall situation. Those who lacked experience had a lower chance of success. 2. ** Dishes Planning ** - There must be a main variety with distinctive business characteristics. Instead of pursuing everything, he should focus on two or three main dishes. For example, it could mainly deal in rice set meals, noodles, snacks, cakes, cold drinks, bar counters, and so on. This was because restaurants usually did not allow the same dish to be operated by multiple companies. Firstly, it was to avoid competition among peers, and secondly, it was to enrich the variety of dishes. At the same time, if there were too many types of business, it would distract energy and increase the cost of employing people. It might cause the boss to look like he had a high turnover, but the profit at the end of the month was low or even a loss. 3. ** Boss Ability ** - The boss should have the ability to operate food and beverage. In reality, many bosses who owned restaurants outside the school but did not know how to cook often failed to hire people to contract windows. This was because the boss didn't know how to control costs, and the profits were easily controlled by the chefs and employees. There might also be situations where the chefs could not open their windows due to their resignation. 4. ** Partner considerations ** - Try to avoid partnering to contract the window. Although it seemed that the partnership could help everyone, in actual work, there were many problems with the partnership contract. If they made money, they would face the problem of profit distribution, and one party might even want to do it alone to obtain more profits. If they did not make money, it was easy for both parties to split up when they invested a lot but had no returns. In contrast, family-run businesses (such as single-family or mom-and-pop stores) would reduce such conflicts. ** 2. Business process ** 1. ** Window selection and positioning ** - The window selected a location similar to a physical store. In some school canteens, entering the first or second window on the left of the canteen might be a better choice because many people had the habit of choosing dishes in turn. In terms of positioning, since the university cafeteria was mainly open to students and teachers (some were open to outsiders), and one of the important reasons why they chose to eat in the cafeteria was that the price was cheap, the window positioning should take the low-cost route. 2. ** Dishes Management ** - The dishes had to be rich and varied. College students came from different places and had different tastes. Some liked sweet, some liked spicy, and so on. Only by providing a variety of dishes could most people's needs be met. 3. ** Health and payment ** - Health was of utmost importance. Cutleries, food, tables, chairs, and so on needed to be handled by someone and could not be ignored. In terms of payment, although some university canteens still had meal cards or cash payment methods, the efficiency was low during peak meal times. Opening various payment channels such as WeChat and AliPay could increase the speed of receiving orders and increase the number of customers. At the same time, the service attitude and dressing of the staff would also affect the business. Only by respecting the customers could they win the respect of the customers. 4. ** Business strategy adjustment ** - The manager must be able to endure hardship, endure loneliness, and be flexible. The food and beverage industry dealt with daily necessities every day and would be fined if they did not meet the hygiene standards. They could not be anxious for success. If the business was not good, they had to consider whether it was due to price, taste, quality, or the fact that the new store was not accepted by the students. They had to adjust the dishes according to the situation, carry out marketing plans, and carry out activities, such as using a single item to attract customers, launching a free meal, adopting a shared shareholder model, etc. They could also build a good relationship with the employees and ask for feedback from the students to improve the business. ** 3. Control of costs and profits ** 1. ** Cost of ingredients ** - In some cases, the cost of ingredients might be affected by the school's management. For example, some schools purchased ingredients in a unified manner. Although they claimed to have food safety guarantees, the price of ingredients might be four to five times higher than the market price. At the same time, the price of student meals was limited to a low price, which greatly reduced the profit margin. 2. ** School commission and other expenses ** - The school may deduct a certain percentage of the turnover (such as 27%), collect utility fees, and a possible deposit (such as 50,000 yuan). There will also be penalties if the hygiene is not up to standard during various inspections. In addition, there might be a situation where the funds would flow to the school management when the card machine was used to collect money. The settlement would only be carried out at the end of the month. During this period, the boss would need to pay the employees 'salaries and other expenses, which would affect the final profit. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
