So, we can say that for any prime number n, n is the only prime number divisible by n. For example, 3 is the only prime number divisible by 3. One could say that "3 is the only threeven prime number". Is that unusual? Perhaps not.

Actually, is it true of all the regular polygons with an odd number of sides, since they don't have a "hypotenuse" (meaning here that there is no internal line that can be drawn from one vertex to another that is longer than any other internal dimension. I'm explaining this badly. But a counter example would be the diagonal on a square being linger than its width. That is not what a hypotenuse is, please tell me if there is a word.)

Of course you aren't going to make a pentagonal manhole cover, but is this saying just a misconstrued version of something like "why are manhole covers circles and not squares"?

if anyone here likes maths, how would you represent "|x| <4" as an interval?? and why??

For example:

State the fredholm alternative for the following integral equation:

u(x) + \int_{0}^{1} (literally any polynomial in x and u(t)) dt = 1

LLMs can't handle this level of abstraction.
