1, "A is several times that of B"
To solve this problem, division is needed. Specifically, you can get the answer by dividing A by B. For example, A is 10, B is 2, and how many times is A larger than B? You can divide 10 by 2 to get 5, so A is five times that of B.
2." B is the score of A. "
To solve this problem, multiplication is needed. You can divide 1 by a to get the answer. For example, a is 10 and b is 2, so how many times is b a? 1 divided by 10 can get 0. 1, so b is 0. 1 times of a, or b is one tenth of a.
Generally speaking, "A is a multiple of B" needs to be calculated by division, and "B is a multiple of A" needs to be calculated by multiplication.
Application of mathematics
1, mathematics: exploring the homology of the universe
Mathematics, as a subject that studies the concepts of quantity, structure, space and change, is not only the basis of science, but also an important tool for human beings to understand the world. In physics, Einstein's theory of relativity and Newton's mechanics are inseparable from the support of mathematics.
Astronomers use mathematics to predict the trajectory of the planet, biologists use mathematics to describe the genetic law of genes, and economists use mathematical models to predict the market trend. Mathematics, like the language of the universe, helps people to overcome unknown obstacles and reveal the order and harmony behind everything.
2. Mathematics: the key to cracking the life code
In daily life, mathematics is everywhere. From the setting of alarm clock in the morning to watching TV at night, from the checkout of supermarket shopping to the investment of bank financing, mathematics is playing a silent role.
It helps people solve daily problems, improve work efficiency and optimize the quality of life. Through mathematics, people can better understand the world around them, grasp the essence of things and become the masters of life. Mathematics is like a key, which opens the door to wisdom and convenience for people.
3. Mathematics: the engine of innovation to shape the future.
In the era of rapid development of science and technology, mathematics, as an important driving force of innovation, is leading human society to a new height. Breakthroughs in artificial intelligence, big data, cloud computing, Internet of Things and other fields are inseparable from the support of mathematics.
Mathematics provides theoretical support and practical tools for the development of science and technology, and is the core force to promote social progress. Looking forward to the future, mathematics will continue to play its unique advantages, lead mankind to explore unknown fields and create a better tomorrow.
