1, we need to know what the ten-point method is. The way to round up ten is to divide a number into two parts so that the sum of these two parts is 10. For example, if we see the number 9, we can divide it into 2 and 7, and the sum of 2 and 7 is exactly 10. This is the basic idea of the ten-point method.

2. In order to understand the method of filling ten more intuitively, you can give a concrete example. For example, if we want to calculate 9+7, we first observe that 9 is very close to 10, so we can divide 9 into 2 and 7, where 2 stands for 10-2=8 and 7 stands for 10-3=7. So 9+7 can become 8+7. We know that 8+7= 15, so 9+7= 15.

We use the same method to calculate other figures. For example, if we want to calculate 8+9, we can divide 8 into 2 and 6, where 2 stands for 10-2=8 and 6 stands for 10-4=6. In this way, 8+9 can become 2+9. We know that 2+9= 1 1, so 8+9= 1 1.

In this way, the addition and subtraction within 10 can be calculated quickly. Moreover, this method can not only help us get the correct answer, but also let us better understand the relationship between numbers.

The benefits of learning mathematics:

1. Cultivate logical thinking ability: Mathematics is a subject that needs rigorous logical thinking. By studying mathematics, we can exercise our logical thinking ability and reasoning ability, so as to better understand and analyze problems. This ability is also very important in daily life and work, which can help us solve problems better and make more informed decisions.

2. Improve problem-solving ability: Mathematics is not only a theoretical knowledge, but also a practical tool. Learning mathematics can cultivate our ability to solve problems and enable us to deal with various practical problems better. This ability is also very important in our work, which can help us solve problems in our work better and improve work efficiency.

3. Enhance innovation ability: Mathematics is a subject that needs pioneering thinking and innovation. By studying mathematics, we can enhance our innovative ability and discover and explore new fields and ideas. This ability is also very important in science and technology, economy and other fields, which can help us to innovate and develop better.
