In this video we introduce the concept of a statement as a sentence that has a truth value: true or false, which we represent with the letters T and F. We also introduce existential quantifiers like: some, sometimes, there is, there exists and universal quantifiers like: all, always none, never. Then, we introduce compound statements which combine simple statements with connectives like: and, or, not and the conditional and we use truth tables to define those connectives and to find the truth values of compound statements. Finally, we give a few examples about the conditional and its negation.
