It turns out that the English expression of mathematical multiplication and division is so authentic.
Recently, I have been using the online courses of Khan Academy to help children learn mathematics, which gives me an insight into how American teachers teach mathematics from the perspective of English, which is quite enlightening.

Because modern mathematics arose and developed in Europe, the ideas and symbols of mathematics are based on the western language system. To my surprise, the difference between English and Chinese in mathematical expression is so great-the English expression of mathematics is so concise, but it is obscure after being translated into Chinese.

Take multiplication as an example. I remember when I was studying multiplication at school, the word "multiplication" was rarely encountered in modern Chinese, especially in daily life, and there was no mathematical expression. Like a symbol that must be remembered. And how is it expressed in English? It's a multiple (and of course a multiple), and then I suddenly realized, isn't this multiple the meaning of multiple? How many times does a number multiply this number? Therefore, if "2 times 3 equals 6" is expressed in English, it means "2 times 3 equals 6". In English, multiplication and multiplication are one word. In Chinese, these are two words. This is the power of English language system in mathematics, which is the most direct, concise and understandable.

Looking at division again, the Chinese word "divide" is also a difficult word to understand. What is "points"? It's hard to see why just by looking at the word. But when I read English, my thoughts suddenly became clear. For example, 9 divided by 3 equals 3, which means "9 divided by 3 equals 3" in English. Isn't this division a concept of "division"? So "divide by" expresses the concept of "divide by whom" very intuitively, so it is easy to understand the concept of division.

In addition, I read dy and dx of power function and calculus, and I can guess the related meaning literally. What a powerful language expression! If children learn math, it is suggested that they read more math English, which will help them better understand math concepts. I am afraid this will reduce the troubles of many children.
