Answer:
Step-by-step explanation:
Patrick thinks that when 'a' is a negative integer and 'b' is a positive,
Let "a = -2" and "b = 3"
a). a - b is positive.
a - b = -2 - 3
      = -5 {negative]
Therefore, statement is False.
(a - b) is negative.
b). b - a is positive.
b - a = 3 - (-2)
    = 3 + 2
    = 5 [Positive]
Statement is True.
c). a - (-b) is negative.
a - (-b) = a + b
     = -2 + 3
     = 1 [Positive]
False.
But it's true when a = -5 and b = 3
a - (-b) = -5 - 3
      = -8 [Negative]
