Look at the order, it's multiplication.

Relevant mathematical knowledge.

In arithmetic, the result of multiplying two or more numbers is called their product or product. When the multiplied number is real or complex, the order of multiplication has no effect on the product, which is called commutativity. When multiplying a quaternion or matrix, or some element of a good algebraic structure, the order has an effect on the product as a result.

This shows that there is no commutative multiplication of these objects.

When there are more than two multiplied objects, a multiplication sign (uppercase ) is often used. It's like the addition of multiple objects is used as a symbol. It is generally agreed that when there is only one object of multiplication, the product is the object itself; When there are no multiplicative objects, it is also possible to agree that the so-called "empty product" is 1.

Ninety-nine multiplication tables and formulas: multiplication tables.

Extended Materials. 1. Introduction.

The multiplication formula is the basic calculation rule for multiplication imitation of Hui car, division, and square in ancient Chinese calculations, and has been used for more than 2,000 years. The ancient multiplication mantra was top-down, from"Ninety-nine-eighty-one"Start, to"One and the same"止, in reverse order of what is now used, so the ancients began with the two words of the multiplication formula"Ninety-nine"As the name of this formula, it is also known as the ninety-nine table, the ninety-nine song, the nine-nine cause song, and the ninety-nine multiplication table.

2. Ancient multiplication table.

Ancient Greece, ancient Egypt, ancient India, and ancient Rome did not have a carry system, and in principle an infinitely large multiplication table was required, so it was impossible to have a ninety-nine table. For example, the Greek multiplication table must list 7*8, 70*8, 700*8, 700*8, 7,000*8, ....... In contrast, since the ninety-nine table is based on the decimal system, 7*8=56,70*8=560,700*8=5,600, 7,000*8=56,000, only 7*8=56 is required.

3. Ancient China.

In the Spring and Autumn Period and the Warring States Period, not only the decimal system was invented, but also the ninety-nine table was invented. Later, it was introduced to Goryeo and Japan in the east, and spread to India and Persia in the west through the Silk Road. The decimal system and the ninety-nine table are an important contribution of ancient China to world culture.

Today, countries around the world rarely use multiplication methods such as Greece.
