∙ 11y agoDeductive reasoning In mathematics, a proof is a deductive argument for a mathematical statement. Deductive reasoning, unlike inductive reasoning, is a valid form of proof. It is, in fact, the way in which geometric proofs are written.
They are usually not valid.
Yes, that is a perfectly valid mathematical operation.
There are an infinite number of twin primes. This is true, but as yet there has not been published a valid proof of it. Perhaps soon someone will publish a valid proof.
Yes, a mathematical expression can have no variables, but such an expression is usually not very useful. An example of a valid expression without variables is: 1+1=2

Pythagoras' theorem is only theorem regarding right angle triangles but it is true.
Yes, although two types of proof are usually needed. Passports are recognized all around the world as valid forms of identification.
You need to provide more detail. Valid for what purpose? It can be valid proof the letter was sent to you but it cannot be valid proof of a contract. Details are important.
Yes it is valid proof of marriage. The joint agreement is signed by both in the presence of winesses.
There is more than one way to prove a given mathematical proposition. If the sequence of reasoning is valid, then the proof is correct. That is all that is required.
They are usually not valid.

It is ALWAYS valid. If you purchased something, the bill of sale is proof of that.
There are an infinite number of twin primes. This is true, but as yet there has not been published a valid proof of it. Perhaps soon someone will publish a valid proof.
In a formal proof, logical reasoning and axioms are used to reach a conclusion. By following the rules of logic and making valid deductions based on the given information, a proof can demonstrate the truth of a statement. Furthermore, the structure of the proof, typically composed of statements and reasons, helps to show the validity of the conclusion.
Well there are a couple of pics but mostly not entirely valid.
