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.
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.
2 is a prime number though…..
Is it Just because it’s the only even one?
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.
