Từ 1 ⇒ 9 có số trang là : (9 - 1) x 1 + 1 = 9(trang)

⇒ Từ 1 đến 9 cần đánh số chữ số là: 9 x 1 = 9(chữ số)

Từ 10 ⇒ 99 có số trang là: (99 - 10) x 1 + 1 = 90(trang)

⇒ Từ 10 đến 99 cần đánh số chữ số là: 90 x 2 = 180(chữ số)

Từ 100 ⇒ 452 có tổng số trang là: (452 - 100) x 1 + 1 = 353(trang) 

⇒ Từ 100 đến 452 cần đánh số chữ số là: 353 x 3 = 1059(chữ số)

Living in a smart city brings many benefits and disadvantages. In this article, I will present some pros and cons of living in a smart city.

The first advantage of living in a smart city is convenience. Information and communications technology is integrated into urban systems, helping to provide public services more effectively. For example, through mobile applications, people can easily search for information about transportation, destinations, and entertainment activities. Furthermore, the smart traffic system helps reduce congestion and save travel time.

Another advantage of smart cities is energy saving and environmental protection. Advanced technologies are applied to manage and use resources effectively. For example, automatic lighting and temperature regulation in buildings help save energy. In addition, the use of smart public transport and self-driving cars helps reduce polluting emissions.

However, living in a smart city also has disadvantages. One of them is the issue of information security. With the widespread use of information technology, the risk of personal information insecurity and privacy violations increases. This requires strong security measures to ensure the safety of people's personal data.

Another drawback of smart cities is their dependence on technology. If technology systems fail or are attacked, public services could be disrupted. This poses challenges for maintaining stability and ensuring security of smart cities.

In short, living in a smart city brings many benefits such as convenience and energy savings. However, it is also necessary to pay attention to information security issues and dependence on technology. To make the most of the advantages and minimize the disadvantages, smart investment and management from city managers is needed.
