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.

### 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.
