In the counting method, vertical rows represent single digits, horizontal rows represent ten digits, vertical rows represent hundreds of digits, horizontal rows represent thousands of digits, and so on. Through this vertical and horizontal arrangement, numerical values with different digits can be expressed intuitively. At the same time, the counting method also follows the principle of one tenth, that is, one in every ten units.
The advantage of counting method is that it can directly represent the numerical size of large numbers, and can easily perform operations such as addition, subtraction, multiplication and division. In addition, the counting method can also be used to represent complex numerical values such as fractions, decimals and negative numbers.
In modern mathematics, the counting method has been replaced by Arabic numerals, but in ancient China, it was a very important mathematical tool. By studying the counting method, we can deeply understand the advanced nature and uniqueness of ancient mathematics in China, and also provide new ideas and methods for the development of modern mathematics.
Learn the skills of mathematical calculation;
1. Make a plan: Make a reasonable study plan and arrange the study time and tasks every day, which can help you master mathematics knowledge better. When making a plan, you should consider your own time and energy to ensure that the plan is feasible. At the same time, ensure the flexibility of the plan and make adjustments as needed.
2. Take notes: Taking notes is a good learning method, which can help you consolidate what you have learned and deepen your memory. When you are in class or reading, you should record the key points and difficulties in time and write down your understanding and feelings. When reviewing, you can turn over your notes to strengthen your memory and understanding.
3. Practice more: Mathematics is a subject that needs more practice. Through continuous practice, we can deepen our understanding of mathematical concepts and formulas and improve our ability to solve problems. In practice, we should pay attention to choosing suitable topics, gradually improve the difficulty and challenge our thinking. At the same time, we should be good at summing up experience and skills, finding our own shortcomings and making targeted improvements.
