3. What is the information of the handbook of math in the fifth grade

Math is the science of infinity.

-- Hermann Outer Some of the beautiful theorems in mathematics have the property that they are extremely easy to generalize from facts, but the proofs are extremely well hidden. Mathematics is the king of sciences.

-- Gauss In the field of mathematics, the art of asking questions is more important than the art of answering them. --Kantor A branch of science is full of life so long as it is full of questions, and the absence of questions signals the termination or demise of independent development.

--Hilbert In the world of mathematics, it is not what we know but how we know it that counts. --Pythagoras A science reaches its true perfection only when it successfully uses mathematics.

-- Marx The level of science in a country can be measured by the mathematics it consumes. --The essence of mathematics is its freedom. --Cantor In the field of mathematics, the art of asking questions is more important than the art of answering them. --No problem touches the human emotions so y as infinity, few other ideas inspire reason to fruitful thought as infinity, and yet no other conception requires so much elucidation as infinity. --Hilbert A branch of science is full of life as long as it is full of questions, and a lack of questions signals the termination or demise of independent development. --Hilbert addition, subtraction, multiplication, division (+, -, * (-), ÷ (∶)) and other mathematical symbols are the most familiar symbols to all of us, because they are indispensable not only in the study of mathematics, but also in almost every day's daily life. Not to mention their simplicity, they were not fully developed until the middle of the 17th century. The French mathematician Hucquet, in his "Trois Arithmetiques", written in 1484, used symbols such as D for addition and M for subtraction. These two symbols first appeared in the German mathematician Widmann's Algorithm of Commercial Rapidity, where he used "+" for excess and "-" for deficiency. By 1514, Hecker of the Netherlands first used "+" for addition and "-" for subtraction.In 1544, the German mathematician Stiefel formally used the words 1544, the German mathematician Stiefel in the "Integer Arithmetic" formally used "+" and "-" to indicate addition and subtraction, these two symbols are gradually recognized as true arithmetic symbols, widely used. The symbol "*" for multiplication was pioneered by the English mathematician Autred. He introduced this notation in The Key to Mathematics, published in 1631. It is said to be a variation of the addition symbol +, since multiplication was developed from the operation of adding the same number together. Later, Leibniz, believing that "*" could be easily confused with "X", suggested that the multiplication sign should be represented by "-", and thus "- " was also recognized. The division symbol "÷" was first used by Varys in England, where it was later popularized. The symbol "÷" was first used by Varys in England, and was later popularized in England. The meaning of division is to divide, and the horizontal line in the middle of the symbol "÷" separates the upper and lower parts of the symbol, which is a visual representation of the word "divide". So far, the four symbols are ready, then far from being universally adopted by the degree of 1, point the wrong decimal point Learning math is not only the correct idea to solve the problem, the specific problem solving process can not be wrong, the difference is not even a fraction of a mile, often lost a thousand miles. The United States of America, Chicago, an old woman living on a pension, in the hospital to perform a minor surgery after going home. Two weeks later, she received a bill from the hospital for $63,440. She saw the large number, could not help but be shocked, horrified by a sudden heart attack, fell to the ground and died. Later, someone checked with the hospital, it turned out that the computer put the decimal point in the wrong place, in fact, only need to pay $ 63.44. A wrong decimal point can kill a person. As Newton said: "In mathematics, the smallest error can not be ignored. 2, Poufeng test One day, the French mathematician Poufeng invited many friends to the home, did a test. Poufeng spread a large white paper on the table, the white paper is filled with parallel lines of equal distance, he took out a lot of equal length of small needles, the length of small needles are half the length of the parallel lines. Poufeng said, "Please feel free to throw these small needles onto this white paper!" The guests did as he said.

Poufeng's statistics were: everyone **** rolled 2212 times, in which the small pins intersected the parallel lines on the paper 704 times, 2210 ÷ 704 ≈ 3.142. Poufeng said: "This number is an approximation of π.

Each time you get an approximation of pi, and the more times you throw it, the more accurate the approximation of pi." This is the famous "Pou Feng". This is the famous "Pope's test".

3, mathematical magician On a summer day in 1981, a mental arithmetic competition was held in India. The performer was a 37-year-old woman in India named Shagunthana.

On that day, she had to compete with a state-of-the-art electronic computer with her amazing mental arithmetic skills. The staff wrote out a large number with 201 digits and asked to find the 23rd root of the number.

As a result of the math, Shagunthana took only 50 seconds to report the correct answer to the audience. The computer, on the other hand, had to enter 20,000 instructions and perform calculations in order to come up with the same answer, taking much more time than Shagunthana.

The story was an international sensation, and Shagunthana became known as a "mathematical magician".
