In mathematics, some formulas or teaching materials might be in a messy state. For example, some of the mathematics textbooks were accused of being disorganized, with missing examples and poor overall cohesion, which made parents feel at a loss when tutoring students. However, many seemingly messy mathematical formulas were actually harmonious and natural in structure. For some mathematical problems, such as the complex problem of dividing a three-digit number by a one-digit number, through specific thinking transformations, such as finding the key numerical relationship (such as the quotient being a two-digit number, the remainder being zero, etc.), using the multiplication formula, and the backward deduction method, one could clear up the thoughts and make the seemingly messy problems orderly. When solving an equation, for an equation like "80 minus x divided by three equals 73", which had two steps of calculation on the left side of the equal sign and involved unknown numbers, he would gradually uncover the veil of unknown numbers by treating a part as a whole, thus solving the seemingly complicated and messy equation. Therefore, even if mathematics looked messy on the surface, through appropriate methods and ideas, one could often find the internal logical relationship.

Its composition includes biological parts (producers, consumers, and resolvers) and non-biological parts (sunlight, water, air, temperature, etc.). - Food chain: It is composed of producers and consumers (first class consumer, second class consumer, third class consumer...). - There were different types of ecosystem, such as forest ecosystem, grassland ecosystem, marine ecosystem, freshwater ecosystem, farmland ecosystem, etc. The biosphere was the largest ecosystem. 5. ** Biological Exploration ** - The basic methods were observation, investigation, experiment, analysis, etc. The main method was the experimental method. - The general process of the experimental method was to raise questions, make assumptions, formulate and implement plans, draw conclusions, express and communicate. In the development of the plan, one had to pay attention to variables and set up a control group. 6. [Cell related] - How to use the microscope - The multiple of the eyepieces multiplied by the multiple of the objective lens = the amplification factor. The greater the amplification factor, the fewer cells could be seen. - The image presented under the microscope was inverted. Wherever the image was in the field of view, the slide would continue to move to the center. - When the light was strong, use a small aperture and a flat mirror; when the light was weak, use a large aperture and a concave mirror. - From the low power scope to the high power scope, the field of view darkened and the number of cells decreased. - When the lens is stained, use the lens cleaning paper to clean the lens. - First, use a low-power scope, then a high-power scope; first, use a coarse focal screw, then use a fine focal screw. After the microscope is done, the field of view is clean and white. The coarse focal screw can adjust the height of the tube. When rotating, look at the objective lens. - The steps of making a temporary slide of oral oral cells were as follows: wipe the slide and cover glass, drop a drop of physiological salt solution in the center of the slide, take oral cells, smear oral cells in the physiological salt solution, cover the cover glass, and dye (the role of the physiological salt solution was to maintain the normal shape of the cells and maintain the normal physiological functions of the cells). - The steps of making the onion temporary mounting slide were as follows: wipe the slide and cover glass, drop a drop of water in the center of the slide, take the onion skin cells, put the skin cells in the water, cover the cover glass, and dye. - The common structure of animal cells and plant cells were cell membrane, nucleus, and plasma.

The recipe of the cloud slice cake was common ingredients + nuts + secret ingredients. The detailed production method was as follows: 1. ** Material preparation ** - 20 kg of glutinous rice, 24 kg of white sugar, 1.5 kg of pork fat, 1 kg of cerealose, 1 kg of honey osmanthus sugar, peanut oil, and salt. - The main equipment included a frying pan, a sieve, a grinder, a blending machine, a sugar storage tank, a cake making machine, a slicing machine, and a steamer. 2. ** Production steps ** - ** Stir-frying **: After removing the impurities, the glutinous rice is first washed with warm water at 35 ° C, then washed with water at 50 ° C, stacked in a big bamboo dustpan for 1 hour, then spread out, dried after about 8 hours, and sifted with a sieve to remove the broken rice. 1 kg of rice was stir-fried with 4 kg of coarse sand. A small amount of peanut oil was added during the stir-frying. There should not be any hard rice core or discolored rice grains. Finally, the stir-fried glutinous rice was sieved. It was round and could not bloom. - ** Aged **: The fried glutinous rice is crushed into powder and stored in a cool warehouse for 3 months to age, so that the glutinous rice powder absorbs moisture and loses its dryness, so that the product meets the requirements of light and refreshing. - ** Warming sugar **: It needs to be done in advance (usually the day before). Mix sugar, oil, and water evenly according to the ratio of sugar: water 100:15 (the boiling water should be poured on the sugar and mixed evenly) and put them into the jar to make them soak each other. - ** Rubbing cake **: pour the cake powder on the chopping board, make a concave shape in the middle, add syrup, and rub it quickly with both hands (if you rub it slowly, it will cause the cake powder to expand due to the moisture in the wet sugar, resulting in the softness of the cake being different; you can also mix it fully in the blending machine). After rubbing it, cover it with a wet cloth and let it stand for a while to make the cake powder soft. - ** Making cake **: First mix a small amount of cake powder with honey osmanthus sugar and beat it into a core, then scoop in the remaining ingredients around to make a cake. After beating it tightly with a wooden square, put it into an aluminum mold or a stainless steel plate and flatten it with a cake press. - Stewed Cake: Cut the pressed cake into four strips, flatten the surface with a bronze mirror, and put the cake into a hot water pot to stew.(Stew at 50 - 60 ° C for 5 - 6 minutes and take out; Stew the cake at 80 - 90 ° C for 1.5 - 2 minutes and take it out. Stewing the cake is to make the starch in the cake powder paste and adhere to the sugar to form a cake base. You must control the time and water temperature well.(High temperature and long time will make the product too hard, otherwise it will be too loose). The cake powder will become more sticky when it is heated. After the cake is formed, it will be taken out of the pot and placed upside down on the platform. The cake bottom and the cake bottom will be combined. The side that is close to the bottom of the mold is the surface, and the other side is the bottom. The cake will be stacked vertically. After all the cake bases produced on the same day are stewed, they will be steamed again. - ** Re-steaming **: Place the shaped cake base vertically on the steaming grid at a certain distance and cover it to steam (the water is slightly open, about 5 minutes is enough, it can be shorter in summer and longer in winter). The purpose is to let the steam seep into the interior, so that the powder is pasted and bonded. The steaming grid should not be too close to the water surface to prevent splashing on the cake base. - ** Slicing **: After steaming again, sprinkle a little cooked dry noodles. While it was hot, use a bronze mirror to flatten and decorate the top, bottom, and four sides of the cake strips. Then put them into an airtight wooden box, cover them tightly with a clean cloth, and let them stand for 24 hours. The purpose is to make the cake base absorb enough water to maintain the texture and prevent pollution and mold. The next day, slice them, cut them, and then pack them immediately.
