[VioEdu TV] Đội THCS2 - Bài dự thi VCK Mùa hè kỳ thú 2022

Hello, teachers, students and friends. We have 4 members from different fields, but we all love math. The first member is Vũ Nhật Minh, 6th grade, Thị Trấn Thắng Elementary School, Bắc Giang Province. Next is Lê Hải Anh, 7th grade, Phù Cừ Elementary School, Hương Yên Province. Next is Phạm Đăng Lưu, 8th grade, Bến Tre City Elementary School, Bến Tre Province. Finally, Nguyễn Thị Mai Lan, 9th grade, Sông Thao Elementary School, Bình Cẩm Khế, Phú Thọ Province. With the theme of the miracle of 0, we will talk about the role of numbers and the history of 0. All the numbers we use today were born very early. But the sign of the number 0 was born the latest. Do you know the interesting history of the number 0? Let's find out together. The number 0 was invented by 3 ethnic groups, India, Babylon and Maya. In the 2nd century BC, the Babylonians and the Mayas used a sign to show the number 0 as a symbol. It is considered a concept that nothing is blank, not a number. In India, in the 7th century AD, the Indians signed the number 0 as a small dot, below the numbers, and they considered the number 0 as a number. At this time, the number 0 was officially born and has scientific significance. In the 10th century AD, the Chinese and the Avatars, although not the inventors of the number 0, but they were the inventors of the number 0 with the shape we know now. After that, the number 0 was exported to other countries and was popularly used like this. The number 0 also has many interesting properties. Some of the properties of the number 0 are as follows. In total, the number 0 is equal to 0. All other natural numbers are equal to 0. The number 0 of all other numbers is equal to 1, which is the main characteristic of the number 0. Hey, what will happen if we win the number 0? Or do you want to share your opinion about the significance of this number? First of all, in mathematics, the number 0 is definitely an indispensable number. The number 0 is not the original number, the original number. The number 0 is the original number between 1 and 1. The number 0 is a very important number. The transition from 0 to 1 is a process from 0 to there, while from 1 to 100, 1,000, can only be multiplied. Although the number 0 does not exist, it is the basis for it. If there is no number 0, we will definitely not be able to write numbers such as people, 100 or 1 billion. For human life, the heat and cold of the heat are expressed in degrees C, and the temperature of the atmosphere is expressed in degrees C. For the computer science field, the number 0 is also expressed as data in the real world of computers. There is a very important saying of Edgar Allan Poe, that number 0 is the beginning of everything. If there is no beginning, nothing will be born, and nothing will end. Those are the wonderful meanings that the number 0 brings to life. Just like what Denis Gildy said, number 0 is definitely nothing but does everything. This is the end of our program. Thank you for listening to our program.
