**They are true in all possible worlds where our logic is valid, which means necessarily true.**

## Are mathematical truths necessary truths?

Introduction. Pure mathematical truths, such as ‘0 < 1’, Fermat’s Last Theorem, the Four-Colour-Theorem, the Fundamental Theorem of the Calculus, the Fundamental Theorem of Algebra, or the Well-Ordering Theorem are **commonly thought to be metaphysically necessary**. It is less common to explain why that is so.

## Is a mathematical statement proved true?

So therefore **a mathematical statement is technically true before it has been proven as it is only a statement**. Fahim Meghji Mr. Collins For example we can say that 1 + 1 is 2. We know this is true because it has been proven to be true.

## Can a mathematical statement be true and false?

In mathematics, a statement is a declarative sentence that is **either true or false but not both**. A statement is sometimes called a proposition. The key is that there must be no ambiguity. To be a statement, a sentence must be true or false, and it cannot be both.

## Is a mathematical statement that is believed to be true that it needs not to be proved?

Axiom. The word ‘Axiom’ is derived from the Greek word ‘Axioma’ meaning ‘true without needing a proof’. A mathematical statement which we assume to be true without a proof is called **an axiom**.

## Are all mathematical statements either true or false?

Brielfy **a mathematical statement is a sentence which is either true or false**. It may contain words and symbols. For example “The square root of 4 is 5″ is a mathematical statement (which is, of course, false).

## Is every statement true or false?

**every statement is either true or false**; these two possibilities are called truth values. An argument in which it is claimed that the conclusion follows necessarily from the premises. In other words, it is claimed that under the assumption that the premises are true it is impossible for the conclusion to be false.

## What does it mean for a mathematical statement to be true?

In general, a statement is true if **whenever the hypotheses are true, the conclusion is**.

## Which statement is always true?

**A tautology** is a formula which is “always true” that is, it is true for every assignment of truth values to its simple components.

## Which statement is always false in math?

Contradiction

**Contradiction**: A statement which is always false, and a truth table yields only false results.

## What do you call the statements that are assumed to be true and do not need proof?

**A postulate** is a statement that is assumed true without proof. A theorem is a true statement that can be proven.

## What principle assumes a true statement?

**Mathematical Induction** is a technique of proving a statement, theorem or formula which is thought to be true, for each and every natural number n. By generalizing this in form of a principle which we would use to prove any mathematical statement is ‘Principle of Mathematical Induction’.

## What is a true statement that can be proven?

**A fact** is a statement that can be verified. It can be proven to be true or false through objective evidence.
