Provide an appropriate response.Indicate True (T) or False (F), and for each false statement find real number replacements for a, b, and c that will provide a counterexample.(A) a - b = b - a(B) (a - b) - c = a - (b - c)(C) a + b = b + a(D) (a ? b) ? c = a ? (b ? c)
What will be an ideal response?
(A) F, a = 1 and b = 2 provides a counterexample
(B) F, a = 3, b = 2, and c = 1 provides a counterexample
(C) T
(D) T
