Review absolute value, and try some practice problems.
What is absolute value?
The absolute value of a number is its distance from .
Example: positive number
The absolute value of is :
Example: negative number
The absolute value of is also :
and are the same distance from , so they have the same absolute value of .

- Absolute values are never negative. So the absolute value of 9 can never be equal to negative 9.

- Is absolute value the opposite of a number. What I mean by this is that if a number was positive, it would be a negative? I am very puzzled by this.(8 votes)
- No. Absolute value is always positive. Since it's the distance a number is from 0, it would always be positive. So, the absolute value of positive 5, would be positive 5. You can apply this to physics too. In one dimensional motion, to the left would be negative displacement, and to the right would be positive displacement, but simply moving without specifying a direction would merely be distance, which is always positive.(17 votes)

- absolute value means whatever is inside will always come out positive, so while you have an incorrect statement without the absolute value bars, | -3 | = | 3 | = 3. Since it is a distance from 0, a negative and a positive equal number will always be the same distance from 0.(10 votes)
