Introduction

In mathematics, the absolute value of a number is a fundamental concept that represents the distance of a number from zero on the number line. It is denoted by two vertical lines, such as |x|, where x is the number. In this article, we will explore the value of $|\overline{6}|$ and determine which statement is true about it.

What is Absolute Value?

The absolute value of a number is its distance from zero on the number line. It is always non-negative, meaning it is either positive or zero. For example, the absolute value of 5 is 5, and the absolute value of -5 is also 5. This is because both 5 and -5 are 5 units away from zero on the number line.

Understanding the Bar Notation

The bar notation, denoted by $\overline{6}$ , represents the number 6. It is a way of writing a number with a bar above it, indicating that it is a specific value. In this case, $\overline{6}$ represents the number 6.

Evaluating the Statements

Now that we have a basic understanding of absolute value and the bar notation, let's evaluate the statements.

A. $|6| \ \textgreater \ 6$

This statement claims that the absolute value of 6 is greater than 6. However, we know that the absolute value of a number is its distance from zero on the number line, and it is always non-negative. Therefore, the absolute value of 6 is 6, not greater than 6.

B. $|6| \ \textless \ 6$

This statement claims that the absolute value of 6 is less than 6. However, we know that the absolute value of a number is its distance from zero on the number line, and it is always non-negative. Therefore, the absolute value of 6 is 6, not less than 6.

C. $|6|$ is the distance between 0 and 6, and the distance is always positive regardless of

This statement claims that the absolute value of 6 is the distance between 0 and 6, and that this distance is always positive. This is true, as the absolute value of 6 is indeed the distance between 0 and 6 on the number line, and this distance is always positive.

Conclusion

In conclusion, the correct statement about the value of $|\overline{6}|$ is C. $|6|$ is the distance between 0 and 6, and the distance is always positive regardless of. This statement accurately reflects the definition of absolute value and the bar notation.
