Absolute values are essentially used for the magnitude (distance) to zero of a number. They are represented by a number inside a vertical bar (e.g., |2|)
E.g.'s:
| 2 | = 2 (the absolute value of 2 is equal to 2)
| -4 | = 4 (the absolute value of -4 is 4)
In terms of rational numbers, it just means to hold the fraction. Rational numbers can be written in a/b (fraction) form.
E.g.'s:
| 1+2/3 | = 1+2/3 (the absolute value of one and two thirds is equal to one and two thirds)
| -1-2/3| = 1+2/3 (the absolute value of -1 minus 2/3 is equal to 1 and 2/3.

Is 2 13 a rational number why or why not?
If you mean 213 then it is a rational number because all integers or whole numbers are rational numbers.
What does absolute value inequality mean?
It is an equation used to anwer an absolute value inequality.
What is the absolute number for 3.2?
If you mean the absolute value: the absolute value of a positive number is the number itself, in this case, 3.2.
Is absolute value of any number positive?
No. The absolute value is non-negative but, to be pedantic, that does not mean positive. The absolute value of 0 is 0 which is NOT positive.
What does absolute vaule mean?
The absolute value of a number (in any dimension) is the positive distance between that number and the origin. For ordinary, real numbers, absolute value is simple; e.g. |5| = 5 and |-4.3| = 4.3. For complex numbers in the form a + bi, the "absolute value" is also the length from that point on the plane to the origin, which, by the Pythagorean theorem, is sqrt(a2 + b2). For example, |4 + 3i| = sqrt(42 + 32) = 5.
