The inequality is a true expression.

### Example Question #5 : How To Do Absolute Value In Pre Algebra

Evaluate

Explanation:

To solve problems with absolute value, first solve inside the absolute value signs.  .

The absolute value of  is  because the negative sign is inside the absolute value signs. Remember the absolute value is the distance from that number to zero on the number line. Therefore, the absolute value is always positive.

### Example Question #6 : How To Do Absolute Value In Pre Algebra

Evaluate the expression.

Explanation:

First, treat the absolute value as a parenthesis, and evaluate the term inside.

The absolute value of any term is its distance from zero. A distance cannot be negative, thus, any negative term in an absolute value will be converted to a positive term.
