Connect and share knowledge within a single location that is structured and easy to search. Context: I'm studying for my discrete mathematics exam and I keep running into this question that I've failed to solve. The question is as follows. My work: My idea was to make a boolean statement and if it's a tautology in a true false table.

That means the statement is always correct. Consider the following definition of mathematical induction adapted from David Gunderson's book Handbook of Mathematical Induction :. Mathematical induction's validity as a valid proof technique may be established as a consequence of a fundamental axiom concerning the set of positive integers note: this is only one of many possible ways of viewing induction--see the addendum at discretee end of this answer.

The principle is as follows:. Well-Ordering Principle: Every nonempty set of voes integers contains a least element. The validity of mathematical induction, in kn context where we are using the WOP to prove the validity of mathematical induction, disrcete established by eiscrete a proof by contradiction. This proof will contain several "steps" or "parts.

If yes, then mathematical induction is a valid proof technique. If not, then it is mere rubbish. We are skeptics, and we think that mathematical induction is a sham hint: a proof by contradiction is about to take place. Is this set empty? Perhaps, but we cannot say for certain at the moment. What does this mean? Do you see the problem now and hence the conclusion of the proof by contradiction? What is wrong with this?

Simply consider the following three assertions that occur within the whhat. The logical issue should now be apparent. Addendum: It may be of interest to other students taking discrete mathematics courses that the form of induction proved above often referred to simply as "induction" is actually equivalent to both strong induction and the WOP. This may be surprising, but there is a good paper about the Equivalence of Three Variations on Inducton for readers who are interested.

The answer I provided takes care of 3 above, but you can explore the other three to show equivalence if desired. Your question seems somewhat doe to me, as it stands, but I'll answer the one in the title, and if the question is updated, I'll address that discrdte. Mathematical what does mean in discrete math can be taken whqt its what jobs can you get with psychology and criminology axiom, independent from the other though, as comments point out, it can be proven as a theorem in common systems like ZF.

The point behind such definitions is to capture define boolean algebra with example intuitive idea - the above starts to capture the distributive property of multiplication, which we know from intuition to be a reasonable idea. Yet, it is possible that we could not prove the above statement without taking it as an axiom. Induction basically says every natural number can be "reached" discreet zero.

That is, if we have proven the statements:. Then, we can build a proof for every natural number. If what does mean in discrete math feel doed that such a strong proof technique has been placed, almost like cheating, in the definition of the natural numbers, one must bear in mind that induction only is valid in the formal mwan. There is an ambiguity in our mind, where we might mix up what does mean in discrete math numbers we obtained from reality with the ddoes in the slick model of Peano.

Induction is an important part of the definition of the model of natural numbers. Then the axiom of induction states:. I'm not sure what else a high school geometry text book might discuss, but let's go with that. The first three all discrehe to logic. The fourth pertains to doscrete natural numbers. That is proof by induction. Now proof by induction looks exactly like that pretty agreeable mewn of the natural numbers I just stated above.

For instance, you could have a number system with the numbers zero, one, two You could define rules for summing Bob with other numbers, and so on. Induction doesn't have to work in this system; a proof by induction just shows that the fact is true for all non-Bob numbers, not for all numbers. Show 9 more comments. Sorted by: Reset to default.

The basic idea behind the equivalence proofs is as follows: Strong induction implies Induction. Induction implies Im Induction. Daniel W. Farlow Daniel W. Farlow It doesn't seem like a trivial statement to me, just hiding a lot inside the assumption of the existence of a predecessor function. The only step I didn't get is why we assumed the base case must be true, which I understood well after the explanation of Daniel's 3rd step through the first sentence of his 5th step.

Show wuat more comments. What does mean in discrete math Brandt Milo Brandt But most of the mathematics people see including things that need induction does not take place in such a system. Instead, it usually takes place in some variation of ZF where it is a theorem following from the axiom of infinity. So sure, we have the Peano axioms "build in", but the fact that they are "build in" is a very important part.

The purpose of my answer is to say why we'd expect induction to be true, based on what manipulations we can do for finite cases. A reader interested in what other axioms induction follows from will have to look elsewhere, but I don't kean the answer will mislead them and I slightly edited one questionable statement idscrete the answer. It is not rigorous, but it is not trying to be. To put the question more precisely, why should one believe that the specified inductive class is actually a ZF set?

It is more questionable than even higher-order induction axioms, while the meta-logical justification that Milo Brandt and I give matheducators. Show 1 more comment. Henry Henry k 9 9 gold badges what does mean in discrete math badges bronze badges. Add a comment. If we can't use axioms for proving theorems, I believe nothing can discrfte proved.

Lehs Lehs If you spaek about Peano axioms that is, an msan scheme of axioms. But maybe you talk about some second-order logic, or uniquness inside ZF? But what does mean in discrete math Peano system is categorical - any two models are isomorphic. You are probably familiar with what are the basic concept of market structure models of Peano.

So I guess I consider induction in an second order definition, even if I can't see wyat. It might be that I include set theory. Common proof methods include: Proof by contradiction Direct proof Proof by exhaustion Proof by induction I'm not sure what else a high school geometry text book might discuss, but let's mmean with that. Do you agree What is a causal risk factor you believe proof by induction works.

What does mean in discrete math Bot 1. For my part I would add geometric proofs to the list, maybe under the title "proof by construction". Wouldn't expect you to write out all of the proofs techniques there are This is an intuitive explanation for why induction works, which is fine. But it does not say anything about this. And it is certainly not a proof that induction works.
