Predicate Logic - What is an example of a predicate term in logic?
Answer
A predicate is defined as an expression that states, for example, "x + 2 = y" (P(x,y)). In the Universe of Discourse, two variables are present: x belongs to the set {1,2,3} and y to the set {4,5,6}. There are two propositions, P(1,4) and P(2,4). P(1,4) states that 1 + 2 = 4, and P(2,4) states that 2 + 2 = 4.
