1, shopping calculation.
Shopping calculation is an indispensable part of daily life, and mathematics also plays an important role in shopping. Need to calculate the price of goods, discounts, taxes, etc. These all require mathematical knowledge.
For example, to calculate the price of a commodity with an original price of 100 yuan after 20% discount, you need to use the knowledge of percentages and decimals. Shopping calculation is easy to understand the relationship between shopping and mathematics, and it is also easier for people to understand the relationship between shopping and economy.
2. Technology.
Science and technology is an important application of mathematics in life. Mathematics is the foundation of the development of science and technology, which is widely used in astronomy, physics, computer science and engineering.
Computer science also needs mathematical knowledge. For example, computer scientists need to use discrete mathematics to study algorithms and data structures. Mathematics plays an important role in real life and is widely used in various fields. For example, big data operation and password transmission all need the support of mathematical knowledge. Therefore, the development of science and technology is inseparable from the application of mathematics.
3. Calculation of family living expenses.
After learning math, you can calculate the cost of your family life. By using the overall planning method, we can arrange the order of things more effectively, thus reducing unnecessary waste and expenditure.
For example, when cooking, the weight of materials can be determined according to the weight of ingredients and the amount of materials used to avoid over-cooking; When shopping, you can make a budget according to the price and quality of goods to avoid unnecessary shopping. Through the method of overall planning, we can better manage the family's living cost and make life more stable and happy.
4. Calculate commodity prices.
Mathematics plays an important role in shopping, calculating prices, discounts and taxes. When shopping in supermarkets or shopping malls, you can use activities such as buy one get one free and discount to calculate the actual price of goods according to the price X discount.
In the computer field, algorithms and data structures are the basis of computer science, and mathematics is an important tool for these algorithms and data structures. In addition, mathematics is also widely used in finance, architecture and other fields.
For example, in the financial field, mathematical modeling and risk management can be used to analyze and predict market trends and risks. In the field of architecture, mathematical theories such as geometry and linear algebra can be used to design and optimize buildings and structures.
