Modulus of a negative integer is always . . . . . . . . . . . . . . . . . .

Answer

To solve the question, we need to understand the concept of modulus (or absolute value) of an integer, particularly a negative integer.

### Step-by-Step Solution:

1. **Understanding Modulus**: The modulus of a number refers to its absolute value. It represents the distance of that number from zero on the number line, regardless of the direction (positive or negative).

2. **Negative Integer Example**: Let's take a negative integer as an example, say -5. The modulus of -5 is calculated as follows:
\[ |-5| = 5 \]
Here, we see that the modulus of -5 is 5, which is a positive number.

3. **Generalizing the Concept**: This concept holds true for all negative integers. If we take any negative integer, say -x (where x is a positive integer), the modulus is:
\[ |-x| = x \]
Again, x is positive.

4. **Conclusion**: Therefore, the modulus of any negative integer is always positive.

### Final Answer:
The modulus of a negative integer is always **positive**.
