What is the absolute value of -89?
The absolute value of -89 is 89.
The absolute value of a number represents its distance from zero on the number line. Regardless of whether the number is positive or negative, its absolute value is always positive. In the case of -89, the distance from zero is 89, so the absolute value is 89.
1. What is absolute value?
Absolute value is a mathematical concept that refers to the distance of a number from zero on the number line. It denotes the positive value of a number, irrespective of its sign.
2. How is absolute value denoted?
Absolute value is denoted by two vertical bars surrounding a number, as in |x|, where x represents the number.
3. Why is the absolute value of -89 positive?
The absolute value is always positive because it represents the distance from zero on the number line. It disregards the negative sign of a number.
4. Is the absolute value of a negative number always positive?
Yes, the absolute value of a negative number is always positive. It allows us to determine the positive value associated with a negative quantity.
5. What is the absolute value of a positive number?
The absolute value of a positive number is the number itself. Since positive numbers are already non-negative, their absolute value remains unchanged.
6. How can I calculate the absolute value of a number?
To calculate the absolute value of a number, remove the negative sign if it exists. If the number is already positive, no change is required.
7. Can absolute value be zero?
Yes, the absolute value of zero is zero. As zero is equidistant from positive and negative numbers on the number line, its absolute value is zero.
8. What is the absolute value of a fraction or decimal?
The absolute value of a fraction or decimal follows the same rule as whole numbers. The negative sign is removed, resulting in a positive value.
9. What is the purpose of absolute value?
Absolute value is used in various areas of mathematics and real-life applications. It allows us to compare magnitudes of numbers, calculate distances, and solve equations involving absolute values.
10. Can absolute value be negative in any circumstance?
No, absolute value is never negative. It always yields a non-negative value as its purpose is to measure distance or magnitude, which cannot be negative.
11. How can I represent the absolute value of a number on a number line?
To represent the absolute value of a number on a number line, identify the number’s position and measure the distance from zero. The resulting distance is the number’s absolute value.
12. Does absolute value change the sign of a number?
Yes, absolute value removes the negative sign from a number and preserves its magnitude. The resulting absolute value is always positive.
