Learn Propositional Logic and Truth Tables: Pure Mathematics for Beginners
Propositional logic also known as statement logic is a very popular technique to represent the idea clearly and accurately. The semantics of logic specify the meaning of a proposition. This story is exploring what are the theories behind the proportional logics and how to solve them. This is a formal way of knowledge representation in Mathematics which is using also in Artificial Intelligence(AI). Logic is a language. Therefore It has lexicon, syntax, semantic mechanisms.

1. Statements with words
A statement(proposition) is a statement where we can definitely say whether completely true or false. But not both together. I will show you how to solve this kind of statements, using semantics.
Truth Values
True - 1 or 'T'
False - 0 or 'F'Examples for propositions; Also these are the atomic statements. They are expressing a single idea.
1.Joe Biden is the current president of US -> True
2.Canberra is the capital of Australia -> True
3.Everyone born in February is intelligent -> False
4.3+4 = 7 -> True
