The first step is to draw a banner in the middle of the pictorial with a suitable background color.
The second step is to write a headline on the painted banner: "multiplication formula"
The third step is to draw a border according to the size of the pictorial to make it more beautiful.
The fourth step is to draw a border below and prepare to write the relevant content of "multiplication formula".
Step five, write the relevant propaganda words about the topic "multiplication formula" in the drawn border.
Step 6: Finally, draw a "multiplication table" in the lower right corner, and the handwritten newspaper will be drawn, which is simple and beautiful.

Multiplication is a shortcut to add up the same numbers. The result of its operation 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 additive quantity. 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 the rectangle does not depend on which side is measured first, which shows the exchange property. 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.
What is multiplication?
Multiplication is one of the four operations. For example, 4 times 5, that is, 4 increases 5 times, or it can be said that 5 4' s are added together.
The ancient Babylonians discovered a long time ago that 1/7 was an infinite decimal and could not be divisible. The figures in the ancient Babylonian reciprocal table are all precise decimals, and they are limited decimals. When they encounter infinite decimals, they will solve them by approximation.
In the process of arithmetic development of various civilizations, the generation of multiplication operation is a very important step. A civilization can successfully develop counting methods and addition and subtraction operations, but it is not so easy to create simple and feasible multiplication methods.
The vertical calculation of multiplication seems simple, but it is necessary to master the formula table of 99 multiplication in advance; Considering this, this vertical calculation is not perfect. It will soon be seen that in the development of mathematics, different civilizations have created different multiplication methods, and some can even abandon the multiplication table completely.
