Nevertheless, it is a proposition because it is either true or false but not both. It is impossible for this sentence to be true sometimes, and false at other times. With the advancement of mathematics, someone may be able to either prove or disprove it in the future. The example above is the famous Goldbach Conjecture, which dates back to 1742.

Aug 17, 2021 · Example \(\PageIndex{2}\): Analysis of a Conditional Proposition. Assume your instructor told you “If you receive a grade of 95 or better in the final examination, then you will receive an A in this course.” Your instructor has made a promise to you. If you fulfill his condition, you expect the conclusion (getting an A) to be forthcoming.
In logic, statements of this kind are called propositions. Definition: a proposition is a declarative statement that has complete meaning and can be true or false. Some examples of propositions are: "Jupiter is the largest planet in the Solar System". "Cats don't like water". "The Earth orbits the Sun". "2 is an even number".
Jul 30, 2024 · A proposition is a mathematical statement such as "3 is greater than 4," "an infinite set exists," or "7 is prime." An axiom is a proposition that is assumed to be true. With sufficient information, mathematical logic can often categorize a proposition as true or false, although there are various exceptions (e.g., "This statement is false").
These properties of the statement include that it must assert or declare something, and it should be either true or false but not both at the same time. That means a proposition is a declarative sentence, either true or false (but not both). We’ll also use “statement” as a synonym for propositions. Let’s look at a few examples to ...
