1, rounding method
Rounding is one of the most commonly used methods to obtain approximate values. Is to keep the required number as an integer, and then round the number after the integer. If the number is less than 5, it is directly discarded; If the number is greater than or equal to 5, go forward 1. For example, take 7.36 as the divisor and take 7.36 as the divisor.
2. Four rooms, six rooms, five rooms and double rooms
Four families, six mouths and five pairs are more rigorous methods to find approximate figures. Keep the required number as an integer, and then divide the number after the integer into four and six. If the number is less than 5, it is directly discarded; If the number is equal to 5, go forward1; If the number is greater than 5, move forward by 2. For example, take 7.36 as the divisor and take 7.36 as the divisor.
The benefits of learning mathematics:
1, cultivate logical thinking ability
Mathematics is a very logical subject, and learning mathematics needs to cultivate logical thinking and reasoning ability. These skills can be applied to various fields, including science, engineering, finance and so on. Having strong logical thinking and reasoning ability can help people solve problems and analyze data more accurately and efficiently.
2, enhance the ability to solve problems
Mathematical problems usually require people to use mathematical knowledge and skills to solve problems. Learning mathematics can help people better understand and apply mathematical models and algorithms, so as to better solve problems in real life. This ability is not only conducive to future career development, but also helpful to personal daily life.
3. Open more possibilities
Mathematics is a basic subject, which can open more possibilities for people. Learning mathematics can help people better understand and apply the knowledge of other disciplines, such as physics, chemistry and computer science. At the same time, mathematics is also the cornerstone of many technical and engineering fields. Mastering mathematics knowledge and skills can open more career development opportunities for people in these fields.
