Absolute value review
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 .

- Of course! There cna be an absolute value for any number(7 votes)
- How is the last question on the review not equal?(40 votes)
- Absolute values are never negative. So the absolute value of 9 can never be equal to negative 9.

- One of the videos talked about how a table leg should be 150 milliliters wide with and absolute deviation of say 2.5. Then, you would use absolute value(4 votes)
- Is there such thing as a "negative zero?"(15 votes)
- No, zero is a neutral number so it can't be positive or negative.(7 votes)
- 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)

- kinda get practice:absolute value to find distance(10 votes)
- will it always be the same?. EX -3=3(7 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.(9 votes)
- This was kinda of easy but if any thinks its hard I can understand.(9 votes)
- are you having big or basically long modulus questions (absolute value questions ) which may include 2 to 3 modulus ; if not i can send you some 10 to 20 ques ...
