Answer 2

Answer:

‘First-order logic is called first-order because FOL which comes ‘first’ in the “logics involving quantifiers”.

Explanation:

• This is because FOL contains variables, function symbols and predicate symbols but allows quantifying only the variables that are elements of the domain.
• Function or relation symbols cannot be quantified using First-order logic.
• First-Order logic is a system of symbolized reasoning where “each sentence or statement” that is broken into the ‘subject and a predicate’.
• In a FOL, a predicate represents only a single subject and is called a “first-order predicate calculus” or functional calculus.
• FOL is used to create computer programs especially using Artificial Intelligence.
