What are the rules of propositional logic?

Propositional logic largely involves studying logical connectives such as the words “and” and “or” and the rules determining the truth-values of the propositions they are used to join, as well as what these rules mean for the validity of arguments, and such logical relationships between statements as being consistent …

What are the disadvantages of propositional logic?

Limitations of Propositional logic:

• We cannot represent relations like ALL, some, or none with propositional logic. Example: All the girls are intelligent.
• Propositional logic has limited expressive power.
