EXAMPLES OF SENTENCES WHICH ARE NOT PROPOSITIONS:
Consider the following sentences
Close the door.
x is greater than 2.
He is very rich
What time is it ?
Read this carefully.
x + z = 10
are not propositions.
REMARK:
If sentence is a question or command , or it is vague or nonsensical, then it cannot be classified as true or false then the sentence cannot be a statement or proposition, as easily seen in the above sentences.
The statements which involve variable or pronoun and there are some information about the variable or pronoun which make the role of variable clear then the sentence becomes statement.
For example in the last sentence if we say that x=3 and z=7 then this become a statement and its truth value is T and if we say x=8 and z=4 then the sentence has its truth value as F.
Here is the rule given below
RULE
If the sentence is preceded by other sentences that make the pronoun or variable reference clear, then the sentence is a statement.
