Discussion Overview

The discussion revolves around the question of why the equation {0}^{3}+{0}^{3}={0}^{3} does not serve as a proof for Fermat's Last Theorem, particularly in the context of the theorem's stipulation regarding positive integers. Participants explore the implications of using zero in the theorem's framework and the nature of the theorem itself.

Discussion Character

  • Exploratory
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant expresses confusion about Fermat's Last Theorem and suggests that if A, B, and C are equal to zero, it could provide a proof.
  • Another participant clarifies that Fermat's Last Theorem applies only to positive integers, which the first participant acknowledges as a missed detail.
  • There is a discussion about the nature of the theorem, with one participant noting that it does not specifically mention triangles, unlike the Pythagorean theorem.
  • Participants reflect on the importance of questioning and investigating mathematical concepts, emphasizing that it is common to overlook details.

Areas of Agreement / Disagreement

Participants generally agree that the theorem applies to positive integers, but there remains some uncertainty about the implications of using zero in the context of the theorem. The discussion does not reach a consensus on the validity of the initial claim regarding zero.

Contextual Notes

The discussion highlights the importance of definitions in number theory, particularly the restriction to positive integers in Fermat's Last Theorem. There are unresolved assumptions regarding the implications of using zero in mathematical proofs.

Hello, It is me again.So i was watching some math videos and i came across Fermat's Last Theorem which was very interesting.But i was confused because i wondered for a second and sayed "well if A,B and C are equal then they could be 0 to prove it" but at the same time i thought "well if it works something like the pythagorean theorem then that would be impossible because if a triangle has 3 sides with the length of 0 then there would be nothing" BUT again i also thought "But Fermat's Last Theorem doesn't say anything about a right triangle or any triangle it is just the formula" So my question is:Why isn't {0}^{3}+{0}^{3}={0}^{3} proof (or on any other power with n>2)

I've moved this thread from Differential Equations to Number Theory as that's a better fit.

From Wikipedia:

In number theory, Fermat's Last Theorem (sometimes called Fermat's conjecture, especially in older texts) states that no three positive integers $a$, $b$, and $c$ satisfy the equation $a^n+b^n=c^n$ for any integer value of $n$ greater than 2. The cases $n=1$ and $n=2$ have been known to have infinitely many solutions since antiquity.
 
oh i didn't realize the "positive number" how stupid of me. Also thanks for moving the thread to number theory. I put it hear because i didn't know where to put it and also thank you for replying

I don't think there's anything "stupid" about investigating theorems. It can be easy to miss details, and so asking about it is smart. :D

In the future, if you are unsure about where to post a thread, just make your best guess (as you did for this thread), and then use the post reporting feature to call the thread to the attention of the staff.

To do so, look for the http://mathhelpboards.com/images/mhb/buttons/report-40b.png icon beneath the post, and click that and you will be presented with a form to enter the reason you're reporting the post. Once you enter the reason then submit the form.

When you report the post, just indicate that you are unsure about whether it's posted in the best forum, and someone on staff will be happy to move the thread if needed. (Yes)
