Understanding Absolute Value

Before we dive into the absolute value of −12, it’s important to have a clear understanding of absolute value itself. The absolute value of a number (denoted by |x|) is always a non-negative value, meaning it is never negative. The absolute value removes the negative sign from negative numbers, making them positive. Positive numbers, on the other hand, remain unchanged when taking their absolute value.

For instance, if we take the absolute value of 5 (|5|), the result will be 5 since 5 is already a positive number. However, if we take the absolute value of −5 (|−5|), it becomes 5 because the negative sign is removed.

Finding the Absolute Value of −12

Now let’s address the question at hand: What is the absolute value of −12? The absolute value of −12 is 12. When we remove the negative sign from −12, we obtain 12 as the result. It is essential to remember that the absolute value is always positive.

Frequently Asked Questions (FAQs)

1. What is the absolute value of 0?

The absolute value of 0, denoted as |0|, is 0 itself since 0 is neither positive nor negative.

2. Can absolute value be decimal or fraction?

Absolute value can be applied to any real number, including decimals and fractions. For example, the absolute value of 3.5 is 3.5, and the absolute value of −⅔ is ⅔.

3. Is the absolute value of a positive number equal to the number itself?

Yes, that’s correct. When taking the absolute value of a positive number, the result will be the number itself. For instance, |8| equals 8, and |1000| equals 1000.

4. What is the absolute value of a negative number?

The absolute value of a negative number is the positive form of that number. For instance, the absolute value of −20 is 20.

5. Can absolute value be negative?

No, absolute value is always positive or zero. It represents the distance from zero and is never negative.

6. What is the relation between absolute value and distance?

The absolute value of a number corresponds to its distance from zero on the number line. It measures how far a number is from zero, irrespective of whether it is positive or negative.

7. Are absolute value and magnitude the same thing?

Yes, in mathematics, the terms absolute value and magnitude are often used interchangeably. They refer to the same concept of measuring the distance from zero.

8. How is absolute value useful in solving equations?

Absolute value is commonly used to solve equations, especially those involving inequalities. It allows us to find the range of possible solutions by considering both positive and negative cases simultaneously.

9. Can the absolute value be negative if it is squared?

No, squaring a number does not make its absolute value negative. The result is always non-negative, or 0 if the original number was 0.

10. Does the absolute value of a number change its sign?

No, the absolute value disregards the sign of a number and always returns a positive or zero value. It does not affect the original sign of the number.

11. Is the absolute value the same as the modulus?

Yes, the term modulus is often used to refer to the absolute value of a number. Both terms represent the distance of a number from zero on the number line.

12. What is the absolute value of infinity?

Infinity does not have an absolute value since it is not a real number. Absolute value is only applicable to real numbers.

Now you have a better understanding of absolute value and its role in mathematics. Remember, when faced with the question of What is the absolute value of −12?, the answer is 12. Absolute value aids us in understanding distances and is a fundamental concept across various mathematical applications.
