To analyze the sum \( p + (-q) \), we can rewrite it as \( p - q \). Since both \( p \) and \( q \) are positive numbers, the result will depend on their relative sizes.
- If \( p > q \), then \( p - q \) is positive and represents the distance from \( q \) moving in the positive direction.
- If \( p < q \), then \( p - q \) is negative and represents the distance from \( p \) moving in the negative direction.
- If \( p = q \), then \( p - q = 0\).
Now, out of the given options, the correct interpretation of the sum \( p + (-q) \) or \( p - q \) can be summarized as follows:
-
If \( p > q \): It is \( p - q \), and you can visualize this as starting at \( q \) and moving a distance of \( p \) to the right (positive direction).
-
If \( p < q \): The absolute value \( |p| \) indicates how far you are from \( q \) in the negative direction.
The best choice to express this generally, without assuming more about the relationship between \( p \) and \( q \), is:
The sum \( p + (-q) \) is the number located a distance \( |q| \) from \( p \) in the negative direction.
When \( p < q\), you're moving left and vice versa, confirming that \( p + (-q) \) could represent different positions based on the values of \( p \) and \( q \).
