6. Interesting knowledge of large numbers: Introduce some interesting knowledge about large numbers, such as the concepts of maximum number, minimum number and infinity, and their applications in daily life.

7. Challenges and future of large numbers: introduce the challenges and future development direction of large number research, and its impact on our life and society.

The application of large numbers in life;

1. Financial field: In the financial field, large numbers are widely used. For example, the market value of the stock market and the contract value of the futures market are very large numbers. In addition, in the insurance industry, the law of large numbers is used to estimate the risk probability and loss amount. All these require accurate calculation and analysis of large numbers.

2. Scientific research: In scientific research, large numbers are also very common. For example, in astronomy, scientists need to deal with huge astronomical figures, such as the distance between galaxies and the mass of stars. In physics, large numbers are also used to describe the interaction between microscopic particles and the motion law of macroscopic objects. All these require high-precision calculation and analysis of large numbers.

3. Computer science: In computer science, large numbers are also widely used. For example, in network communication, a large number of data packets and traffic need to be processed, which requires the operation and processing of large numbers. In addition, in cryptography, large numbers are also used to construct secure encryption algorithms and protocols to protect the confidentiality and integrity of data. All these require efficient operation and large number processing.
