1, calculated daily
The most basic application of mathematics in daily life is calculation. We calculate the price when shopping, do numerical analysis when budgeting, adjust the proportion of ingredients when cooking, and so on, all by mathematics.
At home, we need to calculate daily expenses, savings plans and repayment arrangements, which involves basic addition, subtraction, multiplication and division operations. When we decide to buy goods, we also need the help of mathematics to compare prices and discounts.
2. Finance
Mathematics plays an important role in the financial field. Personal finance, loan calculation and investment analysis all need the support of mathematics. Compound interest and discount rate are important concepts to understand the return on investment and the cost of debt. People use mathematics to calculate interest rates, investment returns and retirement plans in order to make wise financial decisions.
3. Data analysis
In the information age, the importance of data is becoming more and more prominent. Statistics and data analysis help us to extract information from a large number of data and make decisions on trends, patterns and relationships. From market research to medical research, data analysis is an important field of mathematical application.
People use mathematical tools and methods to collect, sort out, analyze and interpret data in order to make reasonable conclusions and predictions. This plays a key role in business decision-making, scientific research and policy making.
The significance and rigor of mathematics;
1, which means
Mathematics is a universal means for human beings to strictly describe and deduce the abstract structure and mode of things, and can be applied to any problem in the real world. All mathematical objects are artificially defined in essence. In this sense, mathematics belongs to formal science, not natural science.
Step 2 be strict
Stiffness is a very important and basic part of mathematical proof. Mathematicians hope that their reasoning and axioms of the definite reason system can be inferred. This is to avoid relying on unreliable intuition to draw wrong "theorems" or "proofs", and there have been many examples in history.
