The Basic Methods of Fraction Reduction
The basic method of fraction reduction was as follows: 1. * * Factoring **: To find the parts that can be reduced by decomposing the numerator and numerator. For example, using the complete square difference formula [a 2 - 2ab + b 2 =(a-b) 2] and the square deviation formula [a 2-b 2 =(a + b)(a-b)] to decompose. 2. * * Reduction **: Reduce the same factor in the numerator and numerator to simplify the fraction. 3. * * General Fraction **: For addition and substitution of a fraction with different predictors, the simplest common numerator must be found, and the fraction must be converted into a fraction with the same numerator before the operation. 4. * * Calculating according to the order of operations **: Calculating according to the order of multiplication and division, then addition and addition. If there are any parenthesis, calculate the formula in the parenthesis first. 5. * * Special Skill **: - * * Reduce first, then calculate **: When calculating the addition and substitution of different decimators, you can first decompose the numerator and the decimal of each fraction into factors, and then calculate after reducing. - * * Whole General Fraction **: For the addition and deduction of a fraction and an integral expression, the whole general fraction method can be used to simplify. - * * Sequential addition, successive general fraction **: When there are many fraction in the fraction addition operation, if you add them from left to right and divide them in turn, the calculation can be simplified. - * * Split-term Elimination Method **: If the difference between the two factors in the decimal of the fraction is 1, you can use a specific formula to calculate the split-term addition method. - * * Inverse evaluation, whole substitution **: For some evaluation problems, you can first find the value of the inverse of the fraction, and then get the value of the original formula. - * * Separation fraction method **: To simplify a fraction by splitting it into the sum or difference of several fraction. - * * Set unit 1 **: If the total amount of work or the total distance is not specified in the distance problem or the engineering problem, you can set it as a unit of 1 to simplify the calculation.

The 8 Basic Steps of Fraction Reduction
The following are the basic steps for fraction reduction: 1. [Factoring: Factoring the numerator and numerator of a quotient. This will help you find the common factor to reduce the number of factors.] 2. Dealing with negative exponents: If there are negative exponents, according to the calculation rules of negative exponents, the negative sign of the exponents represents the reciprocals, and it is converted into the form of positive exponents. 3. Observe the order of operations: first multiply, then multiply and divide, then add and subtract. If there are parenthesis, calculate the ones in the parenthesis first. 4. Dealing with the operation of the fraction and the whole expression: Treat the whole expression as a fraction structure with a quotient of 1, and then perform the operation according to the law. 5. Division to multiplication: If there is a division operation, it must be converted into a multiplication operation, which is to multiply the numerator and numerator of the division by the division. 6. Reduction: Find the common factor of the numerator and the decimal to reduce the fraction into the simplest form. However, you must pay attention to judging the fraction before the reduction. You cannot judge the relevant properties of the fraction after the reduction. 7. Combining similar terms: For similar terms in the fraction, such as similar terms in the numerator and numerator or similar terms in the parenthesis, they are combined and simplified. 8. Checking the Denominator: Make sure that the Denominator in the process of reduction is not 0, and at the same time, make sure that the original fraction and the fraction that appears in the process of reduction are meaningful during the final substitution evaluation.

Ten Techniques of Fraction Reduction
The technique of fraction reduction was as follows: 1. First reduce, then general division method: When calculating the addition and substitution of different decimators, you can first decompose each fraction's numerator and decimator into a factor, and then carry out subsequent calculations after reducing. 2. The grouping general fraction method: According to the characteristics of the fraction, the grouping general fraction method is used to simplify the calculation. 3. Item-by-item general division method. 4. Separation fraction method: Separates the fraction reasonably to simplify it. 5. The method of splitting items. 6. [Whole general division, and then simplify: For the addition and deduction of a fraction and an integral expression, the whole general division can be simplified to solve the problem.] 7. Sequential addition, general fraction, and calculation: When multiple general fraction in the fraction addition operation is troublesome, observe the characteristics of the decimal, add them from left to right, and then divide them in order to simplify the calculation. 8. Split-term elimination method: If the difference between the two factors in the fraction's numerator is 1, the split-term addition method can be used to calculate. 9. Reciprocal evaluation, global substitution: When the fraction structure presents certain characteristics, it can be solved by calculating the reciprocals and global substitution. 10. In some cases, it would be easier to simplify the false fraction into the form of the sum of the whole fraction and the true fraction. "Prosperous Brocade Record" is equally exciting.

What are the methods of physical fever reduction?
The physical method to reduce the fever was as follows: 1. ** Wiping bath method **: - You can use 28 - 30 ° C cold water or 75% alcohol diluted with 2 times water (children can adjust the water temperature appropriately), wet it with a small towel and wipe the head, back, limbs, neck, armpits, groin and other parts with rich blood flow. - You can also use warm water of 30 - 37 ° C to wipe the body, including the neck, armpits, groin, palms, arms, back, etc., but it is best not to wipe the back of the child's head, chest, navel, and soles. 2. ** Wetting Method **: - Cold compress could be applied to the forehead, wrists, calves, neck, armpits, groin, and other blood-rich parts with a wet cold towel or an ice pack wrapped in a towel. At the same time, cover other parts with clothes. It was suitable for people whose body temperature was not too high. 3. ** Ice carpet cooling method **: The principle of cooling is used to cool the distilled water in the water tank. Through the work of the host and the water in the blanket, the cooling effect is achieved. 4. ** Cold Saline Enemas **: Use 30 - 32 ° C cold physiological salt water to repeatedly clean and enemas to gradually lower the body temperature to normal. 5. Warm bath: Soak the body in warm water that is slightly lower than body temperature and dissipate heat through heat transfer. However, this method is less applicable in clinical practice. 6. ** Replenish the patient with water **: Drink more plain water to promote blood circulation and accelerate the discharge of the virus. 7. ** Other methods **: - She gave the child ginger and onion water to let the child sweat away the heat. - Give the child more hot water first, don't cover the child's sweat, wash the child's feet with warm water, rub the child's hands and feet hot, put an ice water pillow under the head and neck, use a towel to apply cold compress on the head, and stick a fever reduction paste on the forehead. - To cool down, wrap the towel around the ice bag and place it on the human body's major arteries such as the forehead, behind the pillow, armpit, groin, etc., but avoid placing it behind the ear, chest, abdomen, Scrotum, feet, etc. The novel "Watching the Moon on Fish Island" is equally exciting.

Three Basic Methods of Writing a Calligraphy
There were three basic methods of Lin Tie: facing, facing away, and facing away. He placed the template in front of him, observed it word by word, and wrote it down. After a period of practice, he would no longer look at the template and directly write the words on the paper. Yi Lin was to pursue the overall charm and artistic conception when writing the template, paying attention to the cohesiveness and reflection of the words. These three methods had different applications and emphasis in the process of copying, which could help calligraphy lovers improve their skills and level.
The Basic Playing Methods of Egg Poker
The game was a card game that used two decks of cards and four people to compete in pairs. The basic rules were as follows: * * 1. Card type and size rules ** 1. * * Card Type ** - Single: For example, A, K, etc., the normal order of size is King, King, A, K, Q, J, 10, 9, 8, 7, 6, 5, 4, 3, 2, but when a card is an advisor (level card), it is second only to the two kings. For example, when playing 2, the order of size would become King, Little King, 2, A, K, Q, J, 10, 9, 8, 7, 6, 5, 4, 3. - Pairs: Two cards of the same kind, such as 55. - Three of a kind: Three cards of the same kind, such as a 666. - Three belt pair: 666 + 77. - Three consecutive pairs: 334455. - Santong Lianzhang: 333444. - Straight: A2345 - 10JQKa (only five cards). - Steel plate: 222333. - Wood: 223344. - Bomb: - Four of the same cards (such as 3333) were bombs, and from four to ten of the same cards were bombs. A straight flush (five straight of the same color, such as 56789 hearts) was also a bomb. The biggest bomb was the King Bomb (two Kings and two Little Kings were used together), followed by 10 bombs, 9 bombs, 8 bombs, 7 bombs, 6 bombs, straight flush, 5 bombs, 4 bombs. The internal size of the bomb was the same as the size of the official card, except that the internal size of the straight flush was the same as the size of the straight and had nothing to do with the color. For example, when playing 2, 2222 would be bigger than AAA-A, and when not playing 2, 2222 would be the smallest bomb. 2. * * Special Card Type ** - Match with Everyone: In the game, the staff of hearts is set as "Match with Everyone". Except for the big and small kings, it can replace any card. For example, when playing 2, the 2 of hearts and 333 were played together, which became four 3s; 4578 plus 2 of hearts could form a straight of 45678 (2 of hearts was used as 6), which was usually used to make up bombs. * * 2. Playing rules ** 1. One card could be played one by one, and the card that was played later would be bigger than the previous one. 2. Two of the same cards can be played together, and the rules are the same as a single card. 3. Three of the same cards can be played at the same time, and the rules are the same as a single card. 4. Four of the same cards were played together as a bomb. The bomb was bigger than all the non-bomb cards. 5. There were two ways to play five cards together: - "3 + 2"(such as 66633). The size of "3 + 2" was only related to the 3 in front and had nothing to do with the 2 behind. - Straight (such as 23456), the size of the straight has nothing to do with the staff, the smallest straight is A2345, the largest is 10JQKa. 6. There were two ways to play six cards together: - Steel plate (such as 222333), the size of the steel plate has nothing to do with the staff officer. - Wooden planks (such as 223344). The size of the wooden planks had nothing to do with the staff officer. * * 3. Upgrade Rules ** 1. The initial hit was 2. The only criterion to determine the ranking was to play all the cards in his hand. The first player (first place) would win. 2. If we get the first or second swim, we will level up by 3 and hit 5 in the next game; the first or third swim will level up by 2 and hit 4 in the next game; the first or last swim will level up by 1 and hit 3 in the next game, and so on. * * 4. Other Rules ** 1. [Welcoming party: The last set of cards from our side. If neither of the two opponents wants it, our Federation will receive it and obtain the right to play.] 2. [Tribute]: - If our side goes up in pairs (first and second), then in the next hand, the other side's third and fourth games need to pay tribute to our side (giving one of the biggest cards, the heart does not participate in the tribute). - If our side was the first to swim and the third to swim, then in the next round, the other side's fourth to swim would have to pay tribute to our side's first to swim, and our third to swim would not have to pay tribute. - If our side was the first to swim and the fourth to swim, then our side's fourth to swim would have to pay tribute to our side's first to swim. The fourth player was the first player in the next round, except for the tribute player. 3. [Return Tribute]: The party who receives the tribute must return a card that is less than or equal to 10 to the party who pays the tribute, except for the level card. When two people returned tributes at the same time, they needed to wait until both of them had confirmed their cards before turning over to let the other party know. 4. * * Tribute Carrying **: As long as there are two kings on the side that pays tribute (if two people pay tribute at the same time, each has a king to carry tribute; if only one person pays tribute, he needs to touch two kings to carry tribute), there is no need to pay tribute. At this point, the first card became the first card of the previous round.
What are the basic methods of novel appreciation?
The basic methods of novel appreciation were as follows: ** I. New Criticists '"Careful Reading" Method ** 1. ** Focus on text elements ** - This method focused on the text of the work, focusing on the analysis and comments on the characters, narration, structure, scene, plot, and details. For example, when analyzing a character, one would pay attention to the character's words and deeds, personality characteristics, relationships between characters, etc. For the plot, one would study the beginning and end of the plot, the rationality and continuity of the plot, etc. - It was different from the traditional "Syllogism" style of commenting on the background of the era, the author's life, the ideology and artistry of the work. Even if one knew little about the author, one could still interpret the content and meaning of the work. 2. ** Confirm the method of expression and analyze the benefits ** - ** Comparisons **: Through comparison, the characteristics of a person or thing are highlighted, making the image more distinct. For example, in character creation, two characters with different personalities or different situations were compared to allow the reader to understand the personality characteristics of the characters more clearly. - "Seeing the big from the small": Capture small events and small people to describe. These seemingly ordinary and small contents contain typical meaning and life philosophy. They can reflect the big theme and have profound social significance. - ** Expression-and-Deconstruction Technique **: To raise or suppress the subject of the article first, and then suddenly change, to the surprise of the reader, so that the article has the effect of ups and downs. ** 2. Appreciation of the Art of Description of the Landscape ** 1. ** The art of describing the social environment ** - ** Combination of Point and Area **:"Area" is the whole, and "Point" is an individual scene (usually a person or object that is more prominent in the scene). When describing social scenes, one must grasp the whole and highlight the key points. - ** Comparisons **: Use the comparison of different people and objects in the scene, or the comparison of the same person and object before and after, to highlight the relevant content. - ** Simple sketch or fine brush drawing **: To highlight the background of the character's activities or the character itself with simple (simple sketch, that is, white brush drawing) or fine (fine brush drawing, that is, fine brush drawing) pen and ink. 2. ** The art of describing scenery ** - ** Description angle ** - ** Perception angle **: Description from the perspective of sight, hearing, smell, taste, etc.(shape, sound, color). It can show the characteristics of the scenery from multiple sides and three-dimensional, and combine them into a diverse and unified artistic whole. From there, it can show the overall view, tone, and overall characteristics of the scenery, and then contain interest and reason. - ** Observation angle **: Including fixed-point observation and changing scenery. - ** Scenery angle **: For example, the combination of far and near, high and low, inside and outside, etc. - ** Description Method ** - ** Fine Brushwork and Line Drawing **: Fine Brushwork (fine drawing) can highlight the characteristics of the main scenery and describe it with thick ink and heavy color to infect the readers, which is more conducive to expressing the theme; Line Drawing (rough drawing) is concise, vivid, and vivid. The combination of the two can complement each other, and it can more comprehensively express the characteristics of the scenery and serve the theme. - ** Description of movement and stillness **: It is divided into the combination of movement and stillness, movement against stillness, and stillness against movement. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What are the basic methods to control the flu?
The basic methods of controlling the flu were mainly to use antivirals, antipyretic analgesics, and Chinese patent medicines. Antiviral drugs can be divided into the following categories according to the mechanism of action: 1. ** Neurannidase Inhibition (NAC)**: It selectively suppresses the activity of Neurannidase, prevents the virus from being released from infected cells and invading neighboring cells, reduces the replication of the virus in the body, and has an suppressive effect on both the A and B viruses. Representative drugs included oseltamivir, zanamivir, peramivir, and so on. In China, oseltamivir granules can be used for the treatment of flu in children <1 year old, zanamivir for children>7 years old, and peramivir for people of all ages. 2. ** Ion Channel M2 Blocker **: Blocking the M2 ion channel of the flu virus, thereby suppressing the virus replication. The representative drugs were amantantine and rimantamin. Amantantine was only effective against the A virus and could suppress the reproduction of the virus. When used with antibiotics, it could treat Septicemia, viral pneumonias, and had a fever-reducing effect. Some compound preparations, such as compound amantdine and amanteline tablets, also contained such ingredients. 3. ** Virus R A Polymerase Inhibition **: For example, Mabalosavir, which mainly inhibited the acidic epo-protein (cap-dependent epo-protein) necessary for the replication of the flu virus. It had outstanding efficacy and only needed to be administered once. It was known as "Super Tamiflu". 4. ** Moroxidine Tablets **: It has an suppressive effect on a variety of viruses (including the H1N1 flu virus, the flu virus, the parainfluenzavirus, the rhinovirus, the coronavirus, and the adeno virus). 5. ** Ribavirin **: It is a broad-spectrum antidote. In and out of the body experiments have shown that it is active against both DNA and DNA viruses. It has an suppressive effect on a variety of viruses such as respiratory syncytial virus, parainfluenzavirus, Herpes simplexvirus, and Herpes zoster virus. Antipyretic analgesics were mainly used to treat fever, headache, muscle soreness and other symptoms, including Aspirin, paracetomine, fluralin, amopyrine, napipen, nimesuli, benornate, etc. However, these drugs were more irritating to the digestive tract, so they should be used with caution in patients with digestive tract ulcers. In addition, there were also some Chinese patent medicines that could be used to control the symptoms of the flu. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Basic knowledge and methods of surviving on a deserted island
The basic knowledge and methods of surviving on a deserted island included the following key elements. The first was water. Maintaining water was the primary task of survival on a deserted island. Water could be obtained by collecting rainwater or purifying seawater. Methods of purifying seawater include boiling, filtering, or using a solar boiler. The second was food. There was a limited source of food on the deserted island, so one needed to learn basic survival skills such as fishing, catching birds, and searching for wild fruits. At the same time, he had to pay attention to which foods were edible and which were poisonous. It was also necessary to build a shelter. You could use branches, leaves, and other natural materials to build a simple shelter. You could also choose a safe location to build the shelter, a high ground away from the waves and floods. Finally, there was the fire source. Fire could not only provide heat, but it could also be used for cooking and signal transmission. These basic knowledge and methods could help people survive on a deserted island.
