Two is the oddest prime of them all.
2 may be the only even prime - that is it’s the only prime divisible by 2 - but 3 is the only prime divisible by 3 and 5 is the only prime divisible by 5, so I fail to see how this is unique.
Exactly, “even” litterally means divisible by 2. We could easily come up with a term for divisible by 3 or 5. Maybe there even is one. So yeah 2 is nothing special.
2 is the prime supreme

The meme works better if it’s 1 instead of 2. 1 is mostly not considered a prime number because a bunch of theorems like the fundamental theorem of arithmetic would have to be reworked to say “prime numbers greater than 1.” However, just because 1 is not a prime number doesn’t mean it’s a composite number, so 1 is a number that is neither prime nor composite.
2 is a prime number, but shit ton of theorems only apply to odd prime numbers, and a lot of other theorems treat 2 as a special separate case, because it behaves weirdly.
I don’t get it, why does adding a hand move to the next prime?
🚨 NERD ALERT🚨
Go define a vector space, nerd.
Go compute the p value of you being cool
Go integrate f(x)= 1/x on the domain (-1,1)

let V be you mom’s vagina, a vector space over the field of pubes. We define my d as a vector such that d is in V. Thus my dick is in your mom’s vagina.

In this vector space p values are not defined, but I can assure you that my pp is > 9000.

The integral of f(x)=1/x from -1 to 1 does not converge, just like how your father is never coming back from buying milk. The principal value of that integral tho is 0, just like the amount of hugs you got as a kid.

math is cool, you just too stupid to get it.
I ain’t reading all that. Classic nerd L

Pretty sure that when we plug in a correction factor for the relative age of the Fediverse userbase, “today’s lucky 10,000” becomes more like “today’s lucky 10 million”
Yo what about my man 9
2 is a prime number though……
Is it Just because it’s the only even one?
Often things hold true for all primes except 2. You come across things like “for all non two primes”
Like what? Genuine question, have never heard of this.
Any examples? Sounds like you mean the reason why one is excluded from the primes because of the fundamental theorem of arithmetic.
No, he’s right. “For any odd prime” is a not-unheard-of expression. It is usually to rule out 2 as a trivial case which may need to be handled separately.
https://en.wikipedia.org/wiki/Fermat's_theorem_on_sums_of_two_squares
It’s not unheard of no, but if you have to rule out two for some reason it’s because of some other arbitrary choice. In the first instance (haven’t yet looked at the second and third one) it has to do with the fact that a sum of “two” was chosen arbitrary. You can come up with other things that requires you to exclude primes up to five.
Okay? Like I said, it’s usually to rule out cases where 2 is a trivial edge case. It’s common enough that “for any odd prime / let p be an odd prime” is a normal expression. That’s all.
And how is “even” special? Two is the only prime that’s divisible by two but three is also the only prime divisible by three.
Well 2 is the outlier because it’s the only even prime. It might not be “special” but it is unique out of all of the prime numbers.
“even” just means divisible by two. So it’s not unique at all. Two is the only prime that’s
evendivisible by two and three is the only prime that’s divisible by three. You just think two is a special prime because there is a word for “divisible by two” but the prime two isn’t any more special or unique in any meaningful way than any other prime.It’s unique because all the others are odd numbers. This is crazy that you’re trying to argue this.
Of couse all the others are odd because otherwise they wouldn’t be prime. All primes after three are also not divisible by three… “magic”. The only difference is that there are is no word like “even” or “odd” for “divisible by three” or “not divisible by three”.
only difference is that there are is no word like “even” or “odd” for “divisible by three” or “not divisible by three”.
Yep, hence why 2 is unique - there is a word to describe numbers that are divisible by 2, and 2 is the only one of those that is a prime number.
It seems that you don’t know what the word “unique” means.
