\(p → q = (p + q) − (p − q)\)
\((−2) → 3\) \(= (-2+3) - (-2-3)\)
\((1) - (-5)\)
\(1 + 5 = 6\)
Answer E
\((−2) → 3\) \(= (-2+3) - (-2-3)\)
\((1) - (-5)\)
\(1 + 5 = 6\)
Answer E

Given that p → q = (p + q) − (p − q) for all integers p and q and we need to find the value of (−2) → 3
To find (−2) → 3 we need to compare what is before the → and what is after it in p → q
=> We need to substitute p with (-2) and q with 3
=> (−2) → 3 = (-2 + 3) − (-2 − 3) = 1 - (-5) = 1 + 5 = 6
So, Answer will be E
Hope it helps!
