Transformation of thought was an important mathematical way of thinking in primary school mathematics. ** I. Concepts and Connotation ** Changing one's thinking was to change the direction of the problem from a different perspective when solving a problem. Its purpose was to find the best way to transform unknown, unfamiliar, and complex problems into known, familiar, and simple problems through deduction and induction, so as to solve the problem smoothly. ** 2. The specific operation method ** 1. ** Form Transformation ** - It was more common in the calculation of the area or volume of a geometric figure. For example, when deducing the area of a quadrilateral, the quadrilateral was transformed into a rectangular shape; when deducing the area of a triangle, the triangle was transformed into a quadrilateral; when deducing the area formula of a circle, the circle was transformed into a rectangular shape; when deducing the volume formula of a cylinder, the cylinder was transformed into a cuboid; when deducing the volume formula of a cone, the cone was transformed into a cylinder, etc. 2. ** Digital Conversion ** - In terms of calculation, for example, in the division of decimals, the decimals were converted into the numbers for calculation, and in the division operation, the division could be converted into the multiplication for calculation. When comparing the sizes of two formulas, you can also convert them. For example, when comparing the sizes of 25 + 47 and 35+35, you can convert them into a form that is more convenient for comparison. For example, you can convert 25 + 47 into 35 + 37, or 35 + 35 into 25+45. You can compare the sizes without calculating. - It was also reflected in the estimation. For example, when judging whether the result of 71 - 19 was greater or less than 50, it could be converted into 71 - 20 or 70 - 20 to think. This would allow students to master the estimation knowledge in a relaxed atmosphere and feel the power of transformation. 3. ** Arithmetic Conversion ** - In the calculation of multiplying two or three digits by one digit, the whole ten or hundred digits multiplied by one digit were first converted into a table multiplication calculation, and then the corresponding number of zeros was added to the end of the product. In solving an equation, as in fourth-grade math, the calculation on the left side of the equation could be converted to a form that could use the multiplication distribution law. ** 3. An example of practical application ** 1. ** Find the volume of an irregular object ** - For example, to find the volume of an irregular stone, because its shape was irregular, it could not be directly calculated with the three-dimensional figure volume formula learned in primary school. For example, if an irregular stone was immersed in a rectangular water tank, the volume of the irregular stone would be converted into the volume of the rectangular water by observing the height of the water surface rising. 2. ** Conversion of numerical relationships ** - For a problem like the formula AB - b = 20, it could be transformed into a vertical formula by analysis. According to b - b = 0, without borrowing, a directly fell to 2, and then the value of b was calculated by substitution. ** IV. Summing Up ** Transforming thoughts was a very practical way of thinking in primary school mathematics learning. It ran through many knowledge blocks such as geometry, calculation, estimation, and so on. It could help students simplify complex problems, cultivate students 'mathematical thinking ability, improve the efficiency of solving problems, and lay a good foundation for subsequent mathematics learning.

Jade was valuable. From the perspective of scarcity, jade was a non-regenerative resource, and its origin was relatively unique. The only main origin that could reach the level of gemstones was Myanmar. In addition, the difficulty of mining and the use of manual mining methods in Myanmar mines led to less raw material output, which made the price of jade raw materials soar. In terms of market demand, with the improvement of people's living standards, the demand for jade increased year by year. As the leader of jade, it was favored by consumers, and the increase in demand pushed the value up. From the perspective of quality determining value, high-quality jade had the characteristics of bright colors, fine texture, and high clarity. For example, the imperial green jade had a full color and pure texture. It was the best of the best and was extremely valuable. The price of jadeite varied according to its quality, size, color, and other factors. The price of high-quality jadeite could reach hundreds of thousands or even millions of yuan. Even if the price of low-quality jadeite ranged from hundreds to thousands of yuan, it also indicated that it had a certain value. The novel "Ledge" is equally exciting.

I don't quite understand the exact meaning of the sentence "Hou Yaohua and Yang Yi have already appeared." If it means that they have already appeared on the crosstalk stage or live broadcast, from the information provided, there are many videos released during the process of them smashing each other and teasing each other. This shows that they have many "appearances" in this kind of interaction scene. However, if it means something else, I'm sorry. According to the information I retrieved, I don't know how to answer.

If you want to use a mobile phone lens to shoot a video of a jewelry detail, you can refer to the following methods: - ** Equipment and settings **: - Choose a suitable phone, ensure that the camera has good image quality, and adjust the phone settings, such as focus mode. Some phones had a special macro mode that could be used to capture the details of the jewelry. If there was no macro mode, you could try to manually focus on the details of the jewelry. - You can use some shooting accessories and auxiliary props, such as special equipment such as a macro lens, to help show the details of the jewelry more clearly, so that the details of the jewelry can be clearly displayed in the video. - ** Lighting **: - Understand the types and properties of light, and choose the appropriate lighting method according to the material of the jewelry. For example, for jewelry materials with strong reflective properties, to avoid direct reflection of strong light into the lens and cause facula, soft side light or backlighting could be used to highlight the texture and cutting surface of the jewelry. - When using natural light, choose the right angle to avoid the light being too strong or too weak. If you use lighting to imitate natural light indoors, you can use some lighting equipment to adjust the light intensity and angle to make the local details of the jewelry clear and layered. - ** In terms of composition and shooting skills **: - Decide on the appropriate camera position and composition method, and use close-up composition to make the jewelry full of images and eliminate unnecessary interference from the surrounding elements. - When shooting, some techniques could be used to increase the motion of the picture, such as moving the phone slightly to show the local details of the jewelry from different angles, or letting the jewelry rotate in front of the camera to show its full details. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

There are several possible reasons why people may have the impulse to do evil in English. Firstly, human nature contains both positive and negative aspects. Everyone has basic instincts and desires, such as the desire for power, wealth or self - satisfaction. If these desires are not properly regulated by moral and ethical values, they may turn into impulses to do evil. For example, the excessive pursuit of wealth may lead a person to engage in unethical or illegal behavior like theft or fraud. Secondly, environmental factors play a role. A person who grows up in a negative environment full of violence, abuse or lack of love may be more likely to develop the impulse to harm others. If they have been constantly bullied or neglected, they may try to take revenge on society or others through doing evil. Finally, psychological problems can also cause people to have evil impulses. Some people may have personality disorders, mental illness or abnormal mental states, which make them unable to control their behavior and give in to negative impulses. For example, people with antisocial personality disorder often show disregard for the rights and feelings of others and are prone to engage in immoral or illegal actions. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
