Dude, I hate it when I wake up as an Egyptian pharoah.

The statement "2 is the only even prime number" sounds unusual at first... But if I consider the definition of "even" as "divisible by 2", then I reach the conclusion that "2 is the only prime number divisible by 2". And... of course it is. If any other number were divisible by 2, it would not be prime.

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.

A question for the reader, then - why do we consider "odd" and "even" to be special properties?

hello math wtf do you mean 0.9 repeating is equal to 1

Wait, someone please answer this very real but very unanswered question. In light of the Artemis 2 mission I've been thinking about zero G a lot. And I must know: do the astronauts with a certain lackluster appendage have to wear boxer briefs because otherwise it would just be floating?

Question: people say that manhole covers are circular because they're the only shape that can't be turned to fall through itself. Am I right that this is also true of equalateral triangles?

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"?

Despite having taught high school geometry, I never TOOK high school geometry. Maybe I will try a proof.... I remember proofs, right?

fuck ai.

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

thx :)

I need to fucking know this. and everyone hates when I ask questions but. is 10 just an arbitrary number we chose bc humans have 10 fingers? like we have 10 100 1000 and we have 10² 10⁶ and so on. we measure a lot of things, especially big things by 10. why? is this just because we all do it? could we have just as easily made 8 our special number?

why is it 10

Write anti LLM test questions!

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.
