Three customers came to a store, eager to buy cakes to catch the train, and the limited time could not exceed 16 minutes. Several chefs said there was nothing they could do, because it took five minutes to bake two sides of a cake, and two cakes could be put in one pot at a time, so it took 20 minutes to bake three cakes. Then there was the chef Lao Li, who said that it only took 15 minutes to think. Do you know how to make a brand?
The origin of mathematics: Mathematics is the oldest subject, and its origin can be traced back to more than 10,000 years ago. However, very little information has been preserved before 1000. So far, only in ancient Egypt and Babylon have systematic mathematical documents been found.
As early as 65,438+05,000 years ago, human beings have been able to describe the images of people and animals quite realistically. This is the earliest evidence of the germination of graphic consciousness. Later, it gradually began to pursue circles and straight lines, thus becoming the earliest prototype of mathematical graphics. In daily life and production practice, counting consciousness and counting system have gradually emerged. Humans have explored a variety of counting methods, including knotting with ropes at first, counting with stones, and further expressing language points with symbols, and gradually developing into the numbers we use today. When graphic consciousness and counting consciousness develop to a certain extent, measurement consciousness appears.
This series of development and evolution has gradually formed a complete mathematical discipline that we are familiar with today, including arithmetic, geometry, algebra, trigonometry, calculus, statistics and probability (in fact, it was originally for people to study gambling) ... and so on, and it is still developing.
* * * Numbers were not invented by * * * people, but originated in ancient India, and were later mastered and improved by * * * people and spread to the west. Westerners call these numbers * * * numbers. Since then, the whole world has agreed with this statement.
* * * Numbers are gradually created by ancient Indians in their production practice.
In ancient India, urban construction needed design and planning, and sacrifices needed to calculate the movements of the sun, the moon and the stars, so mathematical calculation came into being. Around 3000 BC, the number of residents in the Indus Valley was relatively advanced, and the decimal calculation method was adopted.
By the third century BC, a complete set of numbers appeared in India, but the writing in different regions was not completely consistent. Brahmanism was the most representative: this set of numbers was widely used at that time. Its characteristic is that every number from "1" to "9" has a special word. Modern numbers are derived from this set of numbers. In this set of numbers, the symbol "0" (zero) has not appeared yet. The number "0" did not appear until Gupta Dynasty (320-550 AD). The symbol "0" was already used in the mathematical book "The Manual of the Sun" completed in the 4th century A.D., when it was only a solid dot. Later, the dot evolved into a small circle "0". In this way, a set of numbers from "1" to "0" tends to be perfect. This is the great contribution of the ancient Indian people to world culture.

"Cleverness lies in diligence, and genius lies in accumulation"-Hua "There is still a 50% hope of success if you persist, and 65,438+0,000% failure if you don't do it." ——————— Wang Juzhen "A person is like a score, his practical ability is like a molecule, and his evaluation of himself is like a denominator. The smaller the score. " -Tolstoy "The essence of mathematics lies in its freedom." -Cantor "In the field of mathematics, the art of asking questions is more important than the art of answering questions." -Cantor "No problem can touch people's emotions as deeply as infinity, and few other thoughts can be stimulated as infinity. However, no other concept needs clarification like infinity. " Hilbert "Mathematics is an infinite science." -Herman Weil "The problem is the core of mathematics. -P.R. Halmos "As long as a branch of science can ask a lot of questions, it is full of vitality. No problem, indicating the termination or decline of independent development. Some beautiful theorems in Hilbert's mathematics have such characteristics: it is easy to sum up from facts, but the proof is extremely profound. Gauss "Time is a constant, but for diligent people, it is a' variable'. People who use' minutes' to calculate time spend 59 times more time than people who use' hours'. " ——————— Ribakov "Dare to do subtraction in learning is to subtract the parts that have been solved by predecessors and see what problems have not been solved. We need to explore and solve it. " -Hua "Genius =2% inspiration +98% sweat." ——— Thomas Alva Edison (Some versions are "Genius = 1% Inspiration +99% Sweat." It is necessary to take time to think about what you have done in a day. If it is'-',we must learn from it and take measures. " -dimitrov "Einstein, the greatest scientist in modern times, wrote a formula when talking about the secret of success: A=x+y+z and explained: A stands for success, X stands for hard work, and Y stands for the correct method. Z stands for less empty talk. " Albert Einstein "Some beautiful theorems in mathematics have the following characteristics: they can be easily summarized from facts, but they have proved to be extremely hidden. Mathematics is the king of science. " -Gauss "In the field of mathematics, the art of asking questions is more important than the art of answering questions." -Cantor "As long as a branch of science can come up with a big number. It is full of vitality, and there is no problem to indicate the termination or decline of independent development. " Hilbert "In the world of mathematics, what matters is not what we know, but how we know it." -Pythagoras "A science can only reach a truly perfect level if it successfully applies mathematics." -karl heinrich marx "The scientific level of a country can be measured by the mathematics it consumes." -Rao "Mathematics-the unshakable cornerstone of science and a rich source of promoting the progress of human cause." -Barrow "The God who rules Mount Olympus is an eternal number." -jacoby "Without the eternal imitation of the universe by numbers, human beings will not continue to exist." -Nietzsche "Those who don't know geometry are forbidden to enter." -Plato "Geometry without Tao is king!" -Euclid Mathematicians are actually fascinated, and if they are not fascinated, there will be no mathematics-Novalis's No Bold Guess, No Great Discovery-isaac newton's Numbers Rule the Universe-Pythagoras's Mathematics, the Queen of Science; Number theory, the queen of mathematics. "-C.F. Gauss" God created integers, and all other numbers are artificial. " -Clone Neck's God is a Mathematician-jacoby "A mathematician without any poetry will never be a complete mathematician." -Wilstrass "The science of pure mathematics will develop again in modern times. It can be said that it is the most primitive creation of the human spirit. " -Whitehead "Number is the world that rules the whole quantity, and the four arithmetic operations can be regarded as all the equipment of mathematicians." -Maxwell "number theory is the oldest branch of human knowledge, but some of his deepest secrets are closely related to his most common truth." -Smith "Infinite! No other problem has touched the human mind so deeply. "-Hilbert" found that every new group is mathematical in form because we can't have other guidance. " -Darwin "The great structure of the universe is now beginning to appear as a pure mathematician." "Meditation" is a reliable law, when the author of mathematics or philosophy works writes in vague and abstruse words. n？ Whitehead "give me five coefficients, and I will draw an elephant;" "Give me six coefficients and the elephant will wag its tail." -Cauchy "Pure mathematics is a magician's real wand." -Novalis "Who doesn't know that the diagonal sides of a square are incommensurable quantities, who doesn't deserve this title." -Plato "The simple composition of integers has been the source of new life in mathematics for centuries." -boekhoff "The incomparable eternity and omnipotence of mathematics and its independence in time and cultural background are the direct consequences of its essence." ——a· Eber "There are only two things in life, developing mathematics and teaching mathematics"-Pershing "Choose the path we should take with all our spiritual strength." However, I feel like a child playing by the sea, picking up a smooth pebble and finding a beautiful shell; In front of me, the sea of truth has not been discovered at all. -isaac newton "I see farther than Descartes, because I stand on the shoulders of giants. -isaac newton "For travelers crossing the bridge, it is impossible to go far without personally checking the firmness of each part of the bridge. Even in the field of mathematics, some things are risky. "-Horace Lamb"
Who can tell me how to write a handwritten newspaper in grade five? The topic is "Mathematics in Labor". What should I write?
Find some math-related questions first, and then illustrate some small patterns with examples in the questions. Here are some math-related questions for you. 1. The clothing workshop brought a batch of cloth to produce a batch of children's clothes. After painting 2.2 meters of cloth, there are still 56 meters left in this batch of cloth. After improving the cutting method, each set only uses 2 meters of cloth, leaving 80 meters of cloth. How many meters is this batch of children's clothes and cloth? A barrel of oil weighs 25 kilograms. After pouring out half, the barrel weighs 13.5 kg. How much does this barrel of oil weigh? There are 93 workers in the workshop of a machine tool factory. In order to improve work efficiency, the plan of reducing staff and increasing efficiency was implemented. Half of the male workers and 30 female workers were arranged to go to work, and the rest of the workers waited at home. The number of male and female workers waiting for work is the same. How many women workers are there in this workshop? Workers bind a batch of books at a fixed time. If everyone binds less 1/5, there will be 360 books left. If each person binds less than 3 copies, there are 180 copies left. How many copies has everyone bound? 5, a piece of land, with three Tieniu brand tractors for 8 hours; It took four tractors nine hours to plow. Now two iron ox tractors and two harvesting tractors plow the fields at the same time. How many hours can you plow? .
