What is the global computing power war

1. How to improve the ability of mathematical calculation

first, the improvement of the ability of calculation requires the study of hard theories and rules.
the correct operation must be based on a thorough understanding of calculation theory. The calculation theory in students' mind is clear and the rules are firmly remembered. When doing four calculation problems, it can be carried out in an orderly way. There are two mistakes in integer multiplication, 25 times 3 equals 95, 24 times 5 equals 100, which typically reflects that students do not have a thorough understanding of multiplication theory in the process of learning arithmetic, and how to deal with the number of multiplication carry is relatively vague. Furthermore, divisor is a decimal division in the two wrong cases (1). 44 divided by 1. 8 equals 8, 11. 2 divided by 0.05 equal to 22.4) also shows that the students' understanding of the law is not deep enough
to understand the meaning of the order and operation law, the operation order refers to the operation of the same level from left to right. In the formula without brackets, if there are addition, subtraction, multiplication and division, multiplication and division should be calculated first, then addition and subtraction; If you have brackets, you should first count the ones in the brackets, and then count the ones in the brackets. Primary school textbooks mainly talk about the law of exchange and combination of addition, and a property of subtraction: "subtracting the sum of two numbers from a number is equal to subtracting two addends from the number in turn." And the commutative law, associative law and distributive law of multiplication. These laws are applicable to the operation of integers, decimals and fractions at the same time, and are widely used. In the two wrong examples [327 - (27 + 75) = 375, 87 times 2 divided by 87 times 2 = 1], both show the students' wrong understanding of the calculation law and the operation law< Second, the improvement of computing power needs to pass, understand and master basic knowledge. In order to get the calculation results, students should first consider what mathematical concepts, operation laws, operation properties, operation rules and calculation formulas to use. Therefore, fully understanding and mastering these basic knowledge determines whether they have the ability of calculation. For example, if students want to have the ability to calculate four items of scores, they must first understand the meaning and nature of scores, understand and master the basic knowledge and corresponding basic skills such as general score, approximate score, the interaction between score and false score. Only when the relevant basic knowledge is explained clearly and the students really master it, the students will not make mistakes in calculation. Compared with the lower grades, the basic knowledge of the higher grades is more abundant. Therefore, we must not rush for success in teaching. We should help students start from sorting out the basic knowledge they have learned, use the transfer, and continue to deepen. For example, when teaching the addition of fractions with different denominators, first ask the students to answer the meaning of addition, and they will know that it is the operation of combining two numbers (or more numbers) into one number. Next, let the students observe and find that the fractions with different denominators and the units of fractions are different, and they can't add directly. After understanding this, they can guide the students to use the knowledge of general division to "turn differences into similarities", So the problem is transformed into the addition of fractions with the same denominator< Third, the improvement of calculation ability needs excellent oral calculation ability.

the new curriculum standard points out: "the basic and developmental nature of mathematics should be highlighted in the compulsory ecation stage." As for the ability of oral calculation, it is the basis of learning mathematics, and the level of oral calculation ability has an extremely important impact on students' basic calculation ability; The training of oral arithmetic is helpful to cultivate students' keen observation; It is helpful to cultivate students' comprehensive thinking ability; It is helpful to cultivate students' quick reaction ability; It is helpful to the cultivation of students' innovative consciousness. How to train the ability of oral arithmetic is an important subject worthy of discussion and research. Teaching practice tells us that it is very necessary to train students' oral arithmetic ability, and we should pay enough attention to it< Fourth, the improvement of computing ability needs to cultivate students' good computing habits.

to improve students' computing ability, we must pay attention to the cultivation of good computing habits< Make students form the habit of proofreading carefully

2. Students are required to see each data and operation symbol clearly, determine the operation order, and choose a reasonable operation method

3. Make students form the habit of careful calculation and standardized writing. Students are required to write neatly, with correct format, correct handwriting, no scribble, no alteration, and keep their homework neat and beautiful< 4. Make students form the habit of estimation and self-conscious checking. Give them the method of checking calculation and estimation, and take checking calculation as an important part of the calculation process to carry out strict requirements, advocating the use of estimation to check the correctness of the answers

5. Make students form the habit of mutual inspection. When a problem has been initially calculated, it can't be calculated completely. It's inevitable for students to make some mistakes in calculation, which requires students to check carefully

6. Be good at drafting.

7. There were two world wars in modern times! They are:
the first World War (abbreviated as World War I, August 1914 November 1918) was a world war that mainly occurred in Europe but spread to the whole world. At that time, most countries in the world were involved in the war

the war process is mainly the battle between central powers and entente powers. Germany, Austria Hungary and Italy are allies, while Britain, France, Russian Empire and Serbia are allies. From 1914 to 1918, many countries in Asia, Europe and America joined the treaty. The battlefield is mainly in Europe. It is worth noting that although Italy is an ally, Britain, France and Russia signed a secret treaty with Italy, promising to give Italy some land. As a result, Italy joined the treaty to fight against the allies

this war is one of the most destructive in European history. About 65 million people took part in the war, about 10 million people lost their lives and about 20 million people were injured

the trigger of the war was the Sarajevo incident in June 1914. The front is mainly divided into the east line (Russia's war against Germany and Austria), the west line (Britain and France's war against Germany) and the South Line 1 (also known as the Balkan front) (Serbia's war against Austria Hungary). Among them, the west line is the most tragic, and the famous battles include the battle of the man river, the battle of Vern and the battle of the Somme river<

Franco Prussia war broke out with France from 1870 to 1871 in order to unify Germany and compete with France for European continental hegemony. The war ended with the defeat of France, the victory of Prussia and the establishment of the German Empire. However, the peace treaty was extremely harsh, which stipulated that France ceded Alsace and Lorraine to Germany and paid 5 billion francs as compensation. As a result, the feud between Germany and France became the cause of the first World War< After the Franco Prussian War, Bismarck, the Prussian prime minister, was worried about French retaliation, so he adopted an alliance policy to encircle France. He originally made Germany form a "three Empire alliance" with Austria Hungary and Russia, but later Russia had a conflict of interest with Austria Hungary because of the Balkan issue at the Berlin Conference in 1878. Finally, in 1879, Germany chose Austria Hungary as its ally and concluded a secret German Austrian alliance with Austria Hungary. In addition, Bismarck turned to form an alliance with Italy, which was isolated because of its conflict with France in colonial affairs and its failure in fighting for North Africa and Tunisia in 1881. Therefore, the German Empire, the Austro Hungarian Empire and the kingdom of Italy concluded a "Three Kingdoms alliance"

when Russia learned that Germany and Austria had signed a German Austrian alliance, it was very angry. But Bismarck was a sophisticated politician. In order to maintain a good relationship with Russia, it signed a treaty with Russia in 1887; Reinsurance treaty;. However, when Bismarck stepped down in 1890, German Emperor William II allowed the treaty to terminate. France, on the other hand, formed an alliance with Russia in 1894 after its financial support for Russia's instrialization. It's for the Franco Russian alliance< However, Britain signed a sincere agreement with France in 1904. This agreement is not a military alliance. This is an agreement to settle the colonial dispute between the two countries. At the instigation of France, Britain and Russia finally ended their colonial dispute in 1907 and signed a British Russian treaty. In the same year, France, Britain and Russia formed the "Three Kingdoms treaty" because of the threat of German power in the Ottoman Empire

since then, Europe has been divided into two camps, so as long as there is any disturbance, there is a possibility that it will turn into a world war. The first World War was caused by the assassination of Archke Ferdinand, the crown prince of the Austro Hungarian Empire< At the beginning of the 20th century, imperialism rose. In the Bismarck era, in view of the establishment of the unified German Empire, the struggle for the colonies was less involved. Later, with the rise of domestic businessmen, businessmen asked the German government to strive for overseas resources and markets. After William II ascended the throne and Bismarck was dismissed, the German Emperor believed that there were too few German colonies and that the raw material procing areas and commodity markets were insufficient. He implemented a "world policy" and demanded that the global sphere of influence be re divided. This is against the interests of the old colonial powers, Britain and France. The first and second Moroccan crises and the vested interests of tsarist Russia also intensified the conflict between the two camps and increased the possibility of war<

the Second World War (1939-1945) is a global war with the largest scale, the heaviest casualties, and the greatest damage to human society
at the peak of the war, 60% of the countries in the world took part in the war, and the war spread to five continents: Asia, Europe, America, Africa and Oceania; At the same time, the two belligerents also fought in the Pacific Ocean, the Atlantic Ocean, the Indian Ocean and the Arctic Ocean. The warring parties in World War II were the anti fascist alliance composed of the United States, the Soviet Union, China, Britain and France, and the fascist axis group composed of Germany, Japan and Italy
although anti fascist resistance such as China's war of resistance against Japan and Ethiopia's war against Italy started before September 1939, it is generally believed that the war began with Germany's invasion of Poland on September 1, 1939 and ended with Japan's surrender to its allies on September 2, 1945
World War II had a far-reaching impact on human beings. The bloody killing and great damage caused by the war have long been reflected in all aspects of human social life after the war. As a result of the war, fascism, a cancer of human society, was eradicated. The political and economic structure of the post-war world is largely the result of the war. In the military field, the war has developed modern military technology, and proced the main way of large-scale use of armored forces to fight. At the same time, strategic bombing has also become an important military means that directly affects the outcome of the war. In the later stage of the war, nuclear weapons were put into the war for the first time and showed their great lethality. The results of World War II fully proved that under the condition of modern technology, the victory of war is directly related to the scientific and technological strength, economic strength, instrial technology level and personnel quality of both sides. World War II also played a significant role in promoting the development of military weapons. Radar, jet fighters, rockets and missiles, computers, nuclear weapons and other high-tech weapons were put into use and played a significant role in the war. These breakthroughs in the military field directly gave birth to the third scientific and technological revolution of postwar mankind< *** The Second World War led to 50 million deaths worldwide, more than any other war in history.

8. World War refers to the global war between opposing groups of countries. In order to achieve their own war goals, the warring parties devoted their national strength to armed struggle and launched a fierce battle on the military, political, economic, cultural, scientific and technological, diplomatic and other fronts. The scale, consumption and harm of the war are very large, causing great disasters to the people of the world.

9. At that time, most countries in the world were involved in the war.
the process of the war was mainly allied countries (German Empire, Austria Hungary Empire, Ottoman Empire, Bulgaria) and treaty countries (the kingdom of Serbia, the Russian Empire, France, Belgium, Germany, Austria, Hungary, Bulgaria) The battle between the British Empire and its colonies (Japan, Montenegro, Romania, Greece, the United States, China, etc.). The German Empire and the Austro Hungarian Empire were allies, while Britain, France, Italy, the Russian Empire and Serbia were allies. From 1914 to 1918, many countries in Asia, Europe and America joined the treaty. The battlefield is mainly in Europe. It is worth noting that although Italy is an ally, Britain, France and Russia signed a secret treaty with Italy, promising to give Italy some land. As a result, Italy joined the treaty to fight against the allies
the war was triggered by the Sarajevo incident in June 1914 [at 9:00 a.m. on June 28, 1914, a young Serb princip (then only 19 years old) assassinated Archke Ferdinand, the crown prince of the Austro Hungarian Empire, who advocated the annexation of Serbia in Sarajevo. This incident, known as the Sarajevo incident, is considered to be the fuse of the first World War. Princip's action is a show of love for the nation, but the Sarajevo incident of the assassination of Ferdinand was used by the Austro Hungarian Empire as a pretext for launching a war against Serbia. On July 23, 1914, Austria, with the unconditional support of Germany, issued an ultimatum to Serbia, including arresting the murderer, suppressing anti Austrian activities and removing anti Austrian officials, which was agreed by Serbia except for its internal affairs. However, Austria will still upgrade its operation. At the same time, Germany was aware of Russia's military mobilization, and the German Emperor asked Russia to stop and prepare for war quickly. In view of the tough diplomacy and pride in the military power of each country, war is inevitable.], The front is mainly divided into the east line (Russia's war against Germany and Austria), the west line (Britain and France's war against Germany) and the south line (also known as the Balkan front, Serbia's war against Austria and Hungary). Among them, the west line is the most tragic, and the famous battles include the battle of the man river, the battle of Vern and the battle of the Somme river
China's participation in the war:
on the issue of whether or not to participate in the first World War to declare war on Germany, the Beiyang government had different opinions and fierce struggle
in order to achieve the goal of the main battle, Duan Qirui called more than a dozen of his supervisors to Beijing to form a "Supervision Corps" to exert pressure on Li Yuanhong, but failed; Later, Duan Qirui asked someone to write a declaration of war against Germany for the president's seal. In order to calm the storm, Li Yuanhong reluctantly sealed the document. Even so, Duan Qirui was still unsatisfied. When the Congress held a meeting to discuss it, he intervened wantonly, which finally touched the public anger< At this time, Duan Qirui's private borrowing from Japan was revealed. On May 21, 1917, Li Yuanhong decided to cancel his post as prime minister. Duan Qirui angrily left Beijing for Tianjin, and pointed out that according to the provisional constitution, the president had no right to cancel his post as prime minister and did not recognize Li's removal order. Because one side is the presidential palace and the other is the State Council, the fight between them is called "the battle between the government and the State Council"
later, Li Yuanhong asked Zhang Xun, head of the Supervision Corps, to come to Beijing on June 14 for mediation. After Zhang Xun entered Beijing, he supported Xuantong restoration. The incident was suppressed by Duan Qirui. Li Yuanhong resigned as president and Feng Guozhang became president. The dispute between the government and the court has come to an end
under Duan Qirui's rule, the Beiyang government, with the support of Britain and France, joined the allies and declared war on them

China's war with Japan was part of the Second World War, and it did not lose< The Second World War was a war against Germany, Italy and Japan. In the end, we won..
