1 and 1 100 million pieces of paper thickness: You can imagine that if 100 million pieces of paper are stacked together, it will be thicker than Mount Everest. Mount Everest is the highest mountain in the world, about 8848 meters high, and the thickness of 100 million pieces of paper will far exceed this height.
2./kloc-the weight of 0/100 million coins:/kloc-the weight of 0/100 million coins is more than four times that of three adult blue whales. The blue whale is the largest known creature, and its adult weight can reach 170 tons, equivalent to 8.5 million coins. So 1 100 million coins weigh more than four times as much as three blue whales, which is a very huge weight.
3.65438+ 100 million grains of rice: If 1 100 million grains of rice are piled together, it can fill the stomachs of 35,000 people. For a person, you need to eat about half a kilogram of rice every day, which is about 500 grains. Then 1 100 million grains of rice can feed 35,000 people a year.
4. 1 100 million primary school students hand in hand: If 100 million primary school students stand in a row hand in hand, then this team can circle the equator of the earth three and a half times. The circumference of the earth's equator is about 40,000 kilometers, and the length of 1 100 million primary school students standing in a row hand in hand will be 3. 5 times this circumference. This is a very long distance, unimaginable.
The fun of math class:
1, Challenging: Mathematics class usually involves the problem-solving process, which requires us to use logical thinking and innovative ability. Whenever we encounter a difficult problem, we can try and correct it by using the mathematical knowledge we have learned, and finally find the correct answer. This problem-solving process can make us feel excited and satisfied, and it is also a pleasure of challenge.
2. Discover new knowledge: Mathematics involves a magical field, in which many laws, formulas and theorems are full of wisdom and beauty. In math class, we can learn many new concepts, theorems and proof methods, which are the crystallization of human wisdom.
3. Widely used: Mathematics is a widely used subject, which not only exists in textbooks, but also involves all aspects of our daily life. By studying mathematics, we can better understand various phenomena and problems in life, such as finance, shopping, architecture and so on.
Mathematics is also the foundation of many other disciplines, such as physics, chemistry, computer science and so on. Therefore, learning mathematics can not only help us better understand the world, but also lay a solid foundation for our future career development.
