To analyze the expression \( p + (-q) \), we can simplify it as follows:
- Since \( p \) and \( q \) are both positive numbers, \( -q \) represents a negative value.
- Therefore, \( p + (-q) \) simplifies to \( p - q \).
Now, we need to interpret what \( p - q \) means in relation to the number line:
- If \( p > q \), then \( p - q \) is a positive number, indicating that the result is located at a distance of \( |p - q| \) from 0 towards the positive direction.
- If \( p < q \), then \( p - q \) is a negative number, indicating that the result is located at a distance of \( |p - q| \) from 0 towards the negative direction.
- If \( p = q \), then \( p - q = 0 \).
Since the question is specifically about the mechanics of the expression \( p + (-q) \), we want to find the phrasing that describes this operation correctly in relation to the distance from \( p \) and \( q \).
Among the given options, the one that correctly and completely describes the situation is:
The sum \( p + (-q) \) is the number located a distance |q| from p in the negative direction.
This interpretation makes sense because when you subtract a positive \( q \) from \( p \), you are effectively moving \( q \) units left from \( p \) on the number line, which corresponds to moving in the negative direction.
