Instead of dividing but dividing, it is the divisor, and 9 is the dividend.
When writing vertically, it becomes 90 7
If it is divided, it is the dividend, and 9 is the divisor.

Thank you. First define it rigorously, and then the equation is a mundane result. In our opinion, this kind of question is the same as the question of "whether 0 is a natural number".
Is 0 a natural number" a mathematical problem? Of course not, it's purely a matter of notation, a question of language about definitions. If you want him to be, if you want him to be, if you want him to be, he won't; But the only way you can get everyone to agree with your answer to this question is to kill everyone who disagrees with you.
As for and 1, they really don't have to be equal. If you accept non-standard analysis, accept hyperreal numbers, accept the existence of 0 infinitesimal as a fixed entity, then you can indeed define it as 1 minus some infinitesimal by something. But if you're using a standard system of real numbers, define the sum of this series, or ,,.
The upper bound of this series of real numbers. That's a very mundane thing, basically synonymous and repeated nonsense. So before discussing a mathematical proposition, make sure you really understand what the proposition is talking about, and make sure that you really understand the meaning of every word and symbol that appears in the proposition.

The number of zero-seven is 9. Nine is the divisor is the divisor, and when it is calculated, it is ten times larger. That's 90 7. Approximately equal to.

In general, unless otherwise indicated, the number of decimal places of the quotient should be as many as the dividend.

<> answer is Jian Chun, like this kind of basic mathematical knowledge, and I also asked my brother to have some multiplication formulas to practice from a young age, and the hereditary foundation is very important.

The vertical type is shown below
If ab=c(b≠0), the operation of finding another factor a using the product c and the factor b is division, written as c b, which is read as c divided by b (or b divided by c). where c is called the dividend, b is called the divisor, and the result a is called the quotient.
For example, in 10 5, the divisor is 10, the divisor is 5, and the quotient is 2. In non-algebraic writing, it is also possible to simply write a b as a b. In most non-English languages, c b can also be written as c:
b。For the use of colons in English, please refer to the scale.

Problem solving ideas: first align the last digit of the two multipliers, then use the second multiplier respectively, multiply a multiplier for each number from the last digit in turn, and finally add up the calculated result to be the product, if the multiplier is a decimal place, it can be expanded by the corresponding multiple, and finally the product is reduced by the corresponding multiple; >>>More
