Note: From activity 1 what one can see is that, we can assign truth value for some sentences and we cannot assign truth value for some other sentences.

Definition

A statement, or a proposition is a declarative sentence which is either true or false but not both.

Example

(a) Addis Ababa is the capital city of Liberia.
This sentence is a statement. The truth value of this statement is true.

(b) 7 + 3 = 16. This is a statement; its truth value is false.

(c) I wish I score 100% in Mathematics test. This sentence is not a statement. We cannot assign the truth value.
