Short description of the topic

Predicate logic - logical connectives

The purpose of Predicate logic is to avoid ambiguity in sentences by forming formulae out of natural language. Logical connectives are used to create formulae out of sentences with "and", "or", "if/then" and "not". The aim is to state if the given sentence is true or false in a given model.

Examples

and

Symbol: Ʌ
Sentence: Harry is a student and Snape is a teacher.
Formulae: [[student (harry) Ʌ teacher (snape)]] = true/false

Truthtable Ʌ
