What is multiplication in English?

Multiplication is multiplication in English. One of the basic operation methods in mathematics, the simplest one is the multiplication of positive integers, that is, a simple algorithm of adding several identical numbers together. Multiply the summand by the number of additions. If 2 is added five times in a row, it must be multiplied by 5. See department.

Definition of multiplication

Multiplication refers to a shortcut to add the same numbers, and its operation result is called product, and "X" is the symbol of multiplication. From the philosophical point of view, multiplication is the result of qualitative change caused by the quantitative change of addition, and the multiplication of integers (including negative numbers), rational numbers (fractions) and real numbers is a systematic summary of this basic definition.

Multiplication can also be seen as calculating the objects arranged in a rectangle (integer) or finding the area of a rectangle with a given side length. The area of a rectangle does not depend on which side is measured first, which shows the commutativity. The product of two measured values is a new type of measurement, for example, multiplying the length of two sides of a rectangle to get its area, which is the theme of size analysis.
