摘要

Having completed our work on propositions, we now move on to the other branch of logic, namely predicate logic. A predicate is a function that contains variables, and outputs a value of true or false. We will learn the notation used for predicates, we will find out how to give values to the variables that a predicate contains, and we will then move on to study some laws which enable us to perform mathematical proofs.
