Is it possible for a decimal number to have absolute value?

Of course! There cna be an absolute value for any number

How is the last question on the review not equal?

Absolute values are never negative. So the absolute value of 9 can never be equal to negative 9. If you look just below the "check" button, you'll see the word "explain". If you click on that, you'll see a more detailed explanation.

What are absolute values in the real world😎😎😎

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

Is there such thing as a "negative zero?"

No, zero is a neutral number so it can't be positive or negative.

is it possible for absolute value to be a decimal?

Yes! If the number is 0.8 the absolute value is 0.8!

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.

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.

will it always be the same?. EX -3=3

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.

What is absolute value?

The absolute value of a number is its distance from

0

Example: positive number

The absolute value of

4

4

Example: negative number

The absolute value of

- 4

is also

4

4

and

- 4

are the same distance from

0

, so they have the same absolute value of

4
