If a sentence is only true or false but not both true and false, then the sentence is called a statement.
Consider the following examples of statements:
a. "The sun rises from the east and sets in the west." Sentences are true.
b. "7 is an odd number". sentence is true.
c. "Water boils at 10 degrees Celsius". sentence is false.
d, "2 is an odd number". sentence is false.
If the examples in Example 1 are studied more deeply, it will be seen that a statement is a sentence that explains something or a declarative sentence. With this it can also be seen that a sentence that does not explain something or is not a declarative sentence is not a statement.
a. Don't try to fight!
b. When did Maradona lead the Argentine national team to the world cup soccer championship?
c. No Smoking!
d. Where do you come from?
Each sentence in example 2 cannot be determined whether it is true or false. Thus, it is in accordance with the previous explanation that example 2 is not a statement.
Although a statement is a sentence that explains something, not all sentences that explain are statements. It seems that what really matters here is whether a sentence can be determined to be true or false or not at all.
a. Mom's cake is delicious.
b. Fandi owns a lot of chickens.
c. Yogyakarta is a safe city.
It seems that all the sentences in example 3 are declarative sentences, but it cannot be determined whether they are true or false because it depends on the circumstances and thus example 3 is not a statement.
Thus the material about the statement, see you in other material and hopefully useful.
