Exercise 1: Let "x - y=z" be denoted by Q(x, y, z), with U as the integers. Find these truth values: Q(4, -1, 3) Q(3,4,1) Q(x, 3, z) Exercise 2: Let "x + y = z" be denoted by P(x, y, z), with U as the integers. Find these truth values: P(1, 2, 3) V P(2, 1, 3) P(1, 2, 3) V P(3, 1, 2) P(1, 2, 3) A P(2, 1, 3) P(1, 2, 3) AP(3, 1, 2) P(1,2,3) P(2, 1, 3) P(1, 2, 3) + P(3, 1, 2) . Exercise 3: Let "x > y" be denoted by P(x, y). Find these truth values: Vx P(x, y) such that x, y as the integers (negative or positive) 3x P(x, y) such that x, y as the integers (negative or positive) Vx P(x+y, y) such that x, y as the positive integers 3x P(x, y) such that x, y as the positive integers Exercise 4: Translating from English to Logic using Predicate Logic and Quantifier "Some students in this class have taken a course in Java."
