On the number axis, the distance from the point representing the number to the origin is called the absolute value of this number, and the absolute value is represented by "| |". On the number axis, a = b, and a > 0, b > 0, then the value of the distance between the point of the number a to the point b is read as the absolute value of a-b, denoted as |a-b|.
For example: |5| refers to the distance between the point representing the number 5 on the number axis and the origin. This distance is 5, so the absolute value of 5 is 5. Similarly, |-5| refers to the distance between the point representing the number -5 on the number axis and the origin. This distance is 5, so the absolute value of -5 is also 5.
The absolute value of the non-negative number [positive number and 0] is itself, and the absolute value of the non-positive number [negative number and 0] is its opposite number.
The absolute value of a is represented by "|a|". Read as "the absolute value of a".
The absolute value of the real number a is always non-negative, ie |a |≥0.
The absolute values of the two numbers that are opposite to each other are equal, that is, |-a|=|a| (since their distances to the origin are equal on the number axis).
If a is a positive number, x satisfying |x|=a has two values ±a, such as |x|=3, then x=±3.
