In mathematics, absolute or modulus |
A non-negative value of x, regardless of its sign, i.e., |
xx denotes positive x, |
xx means negative x (-x is positive in this case), |
For example, the absolute value of 3 is 3, and the absolute value of -3 is also 3. The absolute value of a number can be considered as the distance from zero.
The generalization of the absolute value of real numbers occurs in a wide variety of mathematical settings, such as complex numbers, quaternions.

Extended Materials. The absolute value of a positive number is itself; The absolute value of a negative number is its opposite.
The absolute value of 0 is still 0. The absolute value of a particular zero is both its own and its opposite.
The absolute value of any rational number is non-negative, which means that the absolute value of any rational number is greater than or equal to 0.
The absolute value of any pure imaginary number is the imaginary part.
absolute value. Computer language.
Medium, positive binary.
The first digit (i.e., the sign bit) is 0, and the binary first digit of a negative number is 1.
In a 32-bit system, the function for finding the absolute value of 4 bytes is abs(x).
Both the algebraic and geometric significance of absolute values reveal the following related properties of absolute values:
1) The absolute value of any rational number is a number greater than or equal to 0, which is the non-negativity of the absolute value.
2) There is only one number whose absolute value is equal to 0, which is 0.
3) There are two kinds of numbers whose absolute value is equal to the same positive number, and these two numbers are opposite to each other or equal.

On the number line, the distance from a number to the origin is called the absolute value of the numbera-b|Represents the distance between a point representing a and a point representing b on the number line. For example:
5|Refers to the distance between the point representing the number 5 and the origin on the number line, this distance is 5, so the absolute value of 5 is 5. Again, |-5|Refers to the distance between the point representing the number -5 and the origin on the number line, this distance is 5, so the absolute value of -5 is also 5. It can also be said that |-5|=
In a nutshell, the absolute value of a positive number is itself. The absolute value of a negative number is its opposite. The absolute value of 0 is still 0.
The absolute value of any rational number is.
Non-negative, i.e. the absolute value of any rational number is 0.

The absolute value of a negative number is a positive number. In mathematics, absolute or modulus | x |is a non-negative value, regardless of its sign, i.e., |x |x represents positive x, | x |x means negative x (-x is positive in this case), |0 | 0。
The generalization of the absolute value of real numbers occurs in a wide variety of mathematical settings, such as complex numbers, quaternions, ordered rings, fields, and vector spaces to define absolute values. Absolute values are closely related to the concepts of size, distance, and norm in a variety of mathematical and physical environments.
Examples of absolute value applications:
1. The absolute value of a positive number is itself; The absolute value of a negative number is its opposite. The absolute value of 0 is still 0. The absolute value of a particular zero is both its own and its opposite.
2. The absolute value of any rational number is a non-negative number, that is, the absolute value of any rational number is greater than or equal to 0.
3. To solve absolute inequalities, we must try to remove the absolute value symbol in the equation and convert it into a general algebraic type to solve it.
4. There are two main ways to prove absolute value inequality: one is to remove the absolute value sign and transform it into a general inequality proof: commutation method, discussion method, and flat method; The second is the use of inequalities:
In this way, it is necessary to divide and combine the formulas in the absolute value, add and subtract terms, and make the formulas to be proved and the known formulas to be connected.

Definition of absolute value.
An absolute value is a number on the number line.
The distance from the point to the origin is marked with "|".to represent. The distance is positive, and there is no negative distance number. In mathematics, the absolute value | x |is a non-negative value, regardless of its sign, i.e., |x |x represents positive x, |x |x means negative x (-x is positive in this case), |0 | 0。
For example, the absolute value of 3 is 3, and the absolute value of -3 is also 3. The absolute value of the number can also be considered as the distance between the lift and the zero.

The absolute value of a negative number is its opposite. Negative numbers are a mathematical term, numbers smaller than 0 are called negative numbers, and negative numbers and positive numbers represent quantities with opposite meanings. The two negative numbers are compared to the size, and the absolute value is larger than the smaller. The largest negative integer is: -1, and there is no smallest negative number.
Negative number. Negative numbers are a mathematical term, numbers smaller than 0 are called negative numbers, and negative numbers and positive numbers represent quantities with opposite meanings. Negative numbers are marked with a minus sign (minus
sign, which is equivalent to a minus sign)" and a positive number marker, such as 5, which represents the opposite of 5. As a result, any positive number preceded by a negative sign becomes a negative number. A negative number is the opposite of its absolute value.
On the number axis, negative numbers are on the left side of 0, and the earliest record of negative numbers is the ancient mathematical work "Nine Chapters of Arithmetic" in China. It is specified in the calculation"Positive is red, negative is black", that is, the red arithmetic chip is used to represent a positive number, and the black number is a negative number. The two negative numbers are compared to the size, and the absolute value is larger than the smaller.
The nature of negative numbers.
1. If the negative numbers are smaller than zero, the negative numbers are smaller than the positive numbers. Zero is neither positive nor negative, then -a<0<(+a.)
2. There is no smallest number in a negative number, and there is no largest number.
3. The negative sign before removing the negative number is equal to the absolute value of the negative number.
4. Fractions can also be used as negative numbers, such as: -2 5
5. The square root of a negative number is represented by an imaginary unit "i". (There is no square root for negative numbers in the range of real numbers).

The absolute value of a negative number.
Also positive. Because the absolute value of a negative number represents the distance of the negative number from the origin, and the distance is not added with a negative sign because you are a negative number, it will always be positive, so the absolute value of a negative number is also equivalent to its opposite.
The absolute value refers to the distance from the corresponding point to the origin point of a number on the axis of the number hole, which is marked by "|".to represent. b-a|or |a-b|Represents the distance between a point representing a and a point representing b on the number line.
In mathematics, absolute or modulus |x|, regardless of its sign, i.e., |x|x represents positive x, |x|x means negative x (-x is positive in this case), |0|=0。For example, the absolute value of 3 is 3, and the absolute value of -3 is also 3. The absolute value of a number can be considered as the distance from zero.

The absolute value of a negative number.
An absolute negative number is an absolute value that represents a negative number.
The absolute value is the distance from the point to the origin of a number on the number line, denoted by "|".to represent. b-a|or |a-b|Represents the distance between a point representing a and a point representing b on the number line.
In mathematics, absolute or modulus | x |, regardless of its sign, i.e., | x |x represents positive x, | x |x means negative x (-x is positive in this case), |0 | 0。For example, the absolute value of 3 is 3, and the absolute value of -3 is also 3. The absolute value of a number can be considered as the distance from zero.
For example: the absolute value of -3. The absolute value of -3 is expressed as: | 3|=-3)=3。

The absolute value of a negative number is positive.
The absolute value is the distance from the point to the origin of a number on the number line, denoted by "|".to represent.
By definition, this number should be no less than 0.
The absolute value of a non-negative number (positive number and 0) is itself, and the absolute value of a non-positive number (negative number) is its opposite.
The absolute value of the real number a is always non-negative.
