A set of all integers divided by 5 by 2 Descriptor please use numerical expressions .

The answer is y=.

Expression. It is a combination of numbers, operators, number grouping symbols (parentheses), free variables, constraint variables, etc., which can be obtained by a meaningful arrangement of numeric values. Constraint variables have a numeric value specified in the expression, while free variables can have a numeric value specified in addition to the expression.

Giving a free variable some numeric designation can give an expression numeric value, even though the expression may not be defined for the value of some free variables. Thus, an expression represents a function, the input of which is a fixed value of a free variable, and its output is the value of the expression that is produced by the result.

For example, the expression x y sets the free variables x and y at 10 and 5, respectively, and its output is the number 2; However, when the y value is 0, it is not defined.

The assignment of an expression and the definition of an operator, as well as the domain in which the numeric value is defined.

Yes, there is a connection.

If two expressions are said to be equivalent, it means that for any fixed value of a free variable, both expressions will have the same output, i.e., they represent the same function.

An expression must be conjunctive. That is, each of its operators must have the correct number of inputs, in the right place. For example, the expression 2+3 is combined; The expression *2+ is not a conjunctive, at least not a general notation of arithmetic.

Expressions and their assignments were formulated in the thirties of the twentieth century by Alonzo Church and Stephen Kleene in their calculus. Calculus to modern mathematics and computer programming.

The development of language has had a significant impact.

Use y to denote the set of all integers composed of all integers divided by 5 divided by 2 then y=

In the new version of the textbook, 0 is stipulated to be a natural number, and if it is less than 5, 5 itself is not counted.

The enumeration method is to write out every element in the set, which is suitable for finite sets.

A set of all positive integers less than 5.

A set of all integers with an absolute value less than 4.

Conception. A set is a collective of concrete or abstract objects with a specific nature. The objects that make up a collection are called the elements of the collection.

For example, the whole Chinese collection, its element is every Chinese. Usually use capital letters such as a, b, s, t,..Represents a set with lowercase letters such as a, b, x, y, ,..

An element that represents a collection. If x is an element of the set s, then x is said to belong to s and denoted as x s. If y is not an element of the set s, then y is said not to belong to s and is denoted as y s.

Numbers divisible by 4 can be written as integer multiples of 4, and the set of all numbers divisible by 4 can be expressed as : before collapse, so the answer is regret:

According to the question, if the number of acres of the brigade is x, then the number x is full of dismantling and walking.

x=5n+1,n n, the set of positive integers is .

So the answer is:

Hello landlord: It's normal for you to have this idea, and I've had it before.

You see|-3|+2=5, isn't it?

In fact, there are mathematical rules for remainders, and the regulations are positive by default.

The answer is yes.

It's normal for you to have this thought, and I've had it before.

You see|-3|+2=5, isn't it?

In fact, there are rules for remainders in mathematics, and the default is positive, that is, the remainder of -8 divided by 5 is not -3, but -3+5=2 [-8=-10+2] If you don't understand, please hi me, I wish you a happy study!

To like is to like, why deny. There are many princes and sons with three wives and four concubines in the Great Zhou Dynasty, and I can say that he was also born in a princely family and was born in Fuken. Like a person, upright, do you need to be timid?
