Which of the following describes the sum p + (−q) where p

and q
are positive numbers??

1 answer

The expression \( p + (-q) \) can be rewritten as \( p - q \). Here, since \( p \) and \( q \) are both positive numbers, the nature of the sum depends on the relationship between \( p \) and \( q \):

  1. If \( p > q \): Then \( p - q \) is positive.
  2. If \( p = q \): Then \( p - q = 0\).
  3. If \( p < q \): Then \( p - q \) is negative.

Therefore, \( p + (-q) = p - q \) can be positive, zero, or negative depending on the relative sizes of \( p \) and \( q \).

In summary, \( p + (-q) \) describes a value that can be positive, zero, or negative based on the comparison between \( p \) and \( q \).
