FAQs:

1. What does absolute value mean?

Absolute value represents the distance of a number from zero on a number line.

2. How is absolute value calculated?

To find the absolute value of a number, simply remove the negative sign if it exists.

3. Why is the absolute value always positive?

By definition, the absolute value disregards the sign and only focuses on the numerical value.

4. Is it possible for the absolute value to be negative?

No, the absolute value is always positive or zero. It cannot be negative.

5. What is the absolute value of 0?

The absolute value of 0 is simply 0 since it has no distance from zero.

6. Can there be more than one absolute value for a number?

No, every number has a unique absolute value. It is consistent and unambiguous.

7. Is the absolute value of -78 the same as the absolute value of 78?
