In mathematics, product refers to the result of multiplication of two or more numbers. The sign of the product is the multiplication sign (×), for example, 2×3=6, where 2 and 3 are multiplicand and 6 is the product. Product is a basic concept and one of the most basic operations in mathematics.

Product can be used to represent the product of multiple identical factors, and it can also be used to represent the product of different factors. For example, 4×4×4 can be written as 4 3, where 4 is a factor, 3 is an exponent, and 4 3 represents the cube of 4. Similarly, 2×3×5 can be written as 2×3×5, where 2, 3 and 5 are different factors.

Products are widely used in mathematics, such as algebra, geometry, calculus, probability and other branches of mathematics. In algebra, product is the result of polynomial multiplication; In geometry, product is one of the basic methods to calculate area and volume. In calculus, product is one of the basic tools to solve definite integral and differential equations.

In probability theory, product is one of the calculation methods of joint probability and conditional probability. In a word, product is a basic concept in mathematics and has a wide range of application values. Through the operation and deformation of product, various mathematical problems can be solved, such as calculation, proof, modeling and so on.

The benefits of learning mathematics

People who are good at math are relatively smart and savvy, and they can show their advantages in dealing with people. The faster you think, the more ways and ideas you have. Cambridge, majoring in financial mathematics at Carnegie Mellon University in the United States, said that studying mathematics has brought her mental exercise and made me pay more attention to the rigor of thinking in my life.

Can manage money better than others. The application of mathematics in life is everywhere. Nowadays, the society is already an information society, and mathematical knowledge is used in financial management and computers. Warren Buffett is very powerful, but Buffett's power is also based on mathematics. Buffett's decision-making process is actually the method of using subjective probability.
