Anonymous users2024-02-06A certain bookstore, the opening of a big reward, all 7% off, all 7% off! "A bookstore's radio was broadcast over and over again. I can't help but take a look. It was in that humble little bookstore that I bought another math friend, "100 Math Stories".
The book was very interesting, with a humorous introduction to all aspects of mathematics, with a few interesting pictures inserted next to it, and many stories told briskly, so that I learned a lot through play. Now I'm going to introduce it to you!
Here are the earliest figures for many countries. The Indians used knotted rope to keep tabs, with the hundredth tied at the top, the ten in the middle, and the individual at the bottom. The red rope represents the soldiers, the green rope represents the grain, and the yellow rope represents the gold nuggets.
Whereas, the numbers of ancient Egypt are represented by pictures. They use small vertical bars to represent single digits; Use a horseshoe or handle to represent the number of tens; Use a rope to measure the length to represent the number of 100 digits, and use a finger to represent the number of 10,000 digits; The lotus flower is used to represent the number of thousands; Use your fingers to indicate the number of 10,000 digits; The millions were too long, so they represented them with a frightened figure with his hands held high, and the larger tens of millions of figures with the sun god. The book also tells the story of many mathematicians, but the one that impressed me the most was the story of Thales and the oil press.
Then. The olive oil harvest has been poor for several years, and the villagers have to ask God for help. Through observation, Thales concluded that there would be a bumper harvest this year, but the Dan folks did not believe it.
Thales began to buy oil presses at low prices. However, it was indeed a good year, and everyone was happy, but there was no oil press. The villagers had no choice but to go to Thales to borrow the oil press.
In this way, Thales relied on his ingenuity and won a large fortune.
After reading these stories, do you become more interested in math? Are you more confident about studying math in the future? So, let's work together and swim happily in the ocean of mathematics together!
Hello, I hope mine is helpful to you, I hope you will find it.

Anonymous users2024-02-05Hua Luogeng was born in Jiangsu Province, and he has loved mathematics since he was a child, and he is very smart. In 1930, 19-year-old Hua Luo returned to Geng to study at Tsinghua University. Hua Luogeng studied hard under the guidance of Professor Xiong Qinglai in Tsinghua University for four years, published more than a dozen articles in a row, and was later sent to the United Kingdom to study and obtain a doctorate.
He had a deep study of number theory and came up with the famous Fahrenheit theorem.
The reporter asked him in an interview: "What is your greatest wish?" ”
His spirit of hard work and perseverance for science and the world is worth learning from. ”
Or Gauss's elementary school math teacher thought that there could be no genius in such a small mountain village, so he did not pay attention to education, and one day in class, he assigned the students a calculation problem, from 1 to 100, he thought that everyone would definitely take a long time to do it,。。
The story of physicist Rutherford, Newton's discovery of the gravitational pull of the earth, the killing of Archimedes, and the herding of sheep by Euler.

Anonymous users2024-02-04I read an interesting math book "Ma Xiaoyue Playing Mathematics", which taught a lot of ways to solve math problems, and now I will share it with you.
One day, Ma Xiaojian and his father went to see the flower fair, the tour guide introduced a largest tulip garden, 18 meters long and 14 meters wide, Ma Xiaojian became interested in this beautiful garden, wanted to know its area, but Ma Xiaojian did not bring paper and pen and did not know where to start, Dad calculated that it was 252 square meters, because he used a quick calculation method. Dad told Ma Xiaodian that the calculation rule of multiplying more than ten times more than ten is: add a single digit and add 10; The sum of the last is multiplied by 10; Multiply single digits; Add the two products together.
Ma Xiaoyue calculates the garden according to his father's method, 18 14 is: 8 4 = 12, 12 10 = 22, 22 10 = 220, 4 8 = 32, 32 220 = 252.
Students, you can also try this method, it is really simple and convenient, have you learned it?
