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.

If you mean 213 then it is a rational number because all integers or whole numbers are rational numbers.

It is an equation used to anwer an absolute value inequality.

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.

If you mean the absolute value: the absolute value of a positive number is the number itself, in this case, 3.2.

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.

No it is not true. The absolute value of a number is simply the value of the number with a positive sign.

I suppose you mean "why do they have the same absolute value". This is because of the way the absolute value is defined. The absolute value is the "distance from zero"; it may help to look at the numbers on a number line to get this clear.

It means that you take the absolute values of different numbers, and then compare them to see which one is greater.

the anserw is two. because absolute value mean the amount away from 0 and two is two numbers away from zero.

If you mean 213 then it is a rational number because all integers or whole numbers are rational numbers.

if no absolute value is used the sum is zero.

The mean absolute deviation of this problem is 6.
