**What is the absolute value of 90?**
The absolute value of a number refers to its distance from zero on a number line, regardless of whether it is positive or negative. In the case of 90, the absolute value is simply the number 90 itself because it is already positive and does not need to be changed.
FAQs about the absolute value of numbers:
1. What is the definition of absolute value?
The absolute value of a number is the distance between that number and zero on a number line, without considering its sign.
2. How do you represent absolute value?
The absolute value of a number is typically represented within vertical bars, for example, |x| represents the absolute value of x.
3. What is the absolute value of a negative number?
The absolute value of a negative number simply turns it into a positive number, as the distance between the negative number and zero remains the same. For example, the absolute value of -7 is 7.
4. What is the absolute value of a positive number?
The absolute value of a positive number does not change, as positive numbers are already at that distance from zero. For instance, the absolute value of 9 is 9.
5. What is the absolute value of zero?
The absolute value of zero is zero itself since zero is neither positive nor negative.
6. Can the absolute value be a negative number?
No, the absolute value is always non-negative, meaning it is either a positive number or zero.
7. What is the absolute value of -90?
The absolute value of -90 is 90, as the distance between -90 and zero is 90 units.
8. Is the absolute value of a number always positive?
Yes, the absolute value of a number is always positive or zero. It disregards the sign of the number.
9. How is absolute value useful in mathematics?
Absolute value is instrumental in various mathematical concepts, such as solving absolute value equations, simplifying expressions, and understanding inequalities.
10. What is the absolute value of a fractional number?
The absolute value of a fractional number follows the same rule as whole numbers. The resulting absolute value will be positive. For example, the absolute value of -3/4 is 3/4.
11. Can the absolute value of a number ever be greater than the original number?
No, the absolute value of a number can never be greater than the original number. It will be equal to or smaller than the original value.
12. How does the absolute value help in finding the distance between two numbers?
When finding the distance between two numbers, we can subtract one number from the other and then calculate the absolute value of the result. This ensures that the distance obtained is always positive, regardless of the order of subtraction.
