What is a complex statement in logic?
A complex sentence is a sentence made up of smaller sentences, for example “Sarah can swim but she cannot dive” is made up of the declarative sentences “Sarah can swim” and “She cannot dive”, linked by the conjunction “but”. Such words and phrases that link other declarative sentences are sentence functors.
What are simple propositions in logic?
Simple propositions are declarative sentences which do not contain a connective. The restriction to declarative sentences is important. In propositional logic each proposition, simple or complex, must be capable of being either true or false. So we won’t count questions or commands, for example, as simple propositions.
What are complex sentences in propositional logic?
Complex sentences are constructed from simpler sentences using logical connectives: ¬ (not), ∧ (and), ∨ (or), → (implies) [I prefer → to ⇒], and ↔ (iff). Every propositional symbol is a sentence. If A is a sentence, then ¬A is a sentence. A world or domain is the set of facts we want to represent.
What are examples of propositions?
For example, “Grass is green”, and “2 + 5 = 5” are propositions. The first proposition has the truth value of “true” and the second “false”. But “Close the door”, and “Is it hot outside?”are not propositions.
What are the types of sentences in logic?
Every sentence in propositional logic is one of six types:
- Simple.
- Negation.
- Conjunction.
- Disjunction.
- Conditional.
- Biconditional.

What is a simple sentence in logic?
Simple sentences in Propositional Logic are often called proposition constants or, sometimes, logical constants. In what follows, we write proposition constants as strings of letters, digits, and underscores (“_”), where the first character is a lower case letter.
How do you write a complex sentence example?
Here’s an example of a complex sentence: Because my pizza was cold, I put it in the microwave. This sentence has an independent clause (“I put it in the microwave”) and a dependent clause (“Because my pizza was cold”) so it’s a complex sentence.
What is the difference between simple and compound proposition?
A proposition represented as a simple sentence is called simple proposition whereas when two or more propositions are joined together with the help of some connecting words then the resulting proposition is said to be ‘Compound Proposition’.
What are the types of proposition in logic?
There are five types in propositional logic:
- Negations.
- Conjunctions.
- Disjunctions.
- Conditionals.
- Biconditionals.
What are complex sentences?
Complex Sentences A complex sentence contains at least one independent clause and at least one dependent clause. Dependent clauses can refer to the subject (who, which) the sequence/time (since, while), or the causal elements (because, if) of the independent clause.
