One concept that I found useful in Truth Tables was a tautology. A compound claim is a tautology if it is true for every possible assignment of truth-values to its parts. In a tautology it doesn't matter whether A is true or false. Any claim with the form A v L A is true. (v representing or and L representing not)
For example, I am a girl or I am not a girl
A v L A
A L A A V L A
T F T
F T T
