Second thought, I think neither.

The definition of a prime number is that its only factors are 1 and itself. 1 fits that definition, 0 does not.

1 isn't a prime number

1 is depending on what book you read. 2 is the first real prime.

0 is hard because it denotes an absence of value.

1 is not a prime number nor is it a composite number. It has a special name but I don't remember.

0 is also not a prime number.

Actually, since he used the word OR, "is" is correct.

Heh, he asks a math question and ends up with an english debate.

"Is 0 or 1 prime?"
"Are 0 and 1 prime?"

 

[dullard]

By mathematical definition, 1 is a prime number. However by convention, 1 is excluded from the list of prime numbers.

Welcome to ATOT :beer:😀

"Is 2 or 3 the correct answer?"

If the question is asking for one exclusive answer, "is" is correct.

Is 0 or 1 prime seems more like "Is 0 prime, or is 1 prime", not "are either of 0 or 1 prime?". Like either one is or the other is, not that neither or both can be.

do your own homework

well zero isnt a number its a concept so 0 is not a prime number because its not a number

1 on the other hand can be considered prime or not

Wrong. "Is 0 or 1 prime" is correct.

 

[AIWGuru]

You have a choice to make here:
"Are 0 and 1 prime numbers?"
OR:
"Is 0 or 1 a prime number?"

The "is" option implies that one of the two is a prime and you're not sure which one. Since you're not sure about either, I would use the "are" option.

Proof that zero isn't a number?

Google says otherwise, although the top sourse is USAToday.....

Hey Dullard, how's it going? I tend to always see you in these threads. 🙂

The correct definition of prime number is: A whole number greater than 1 that is divisible by only itself and 1. Most teachers seem to forget to include the first part about being greater than 1. The reason for prime numbers is for prime factorization (factoring something completely into its components).

Every number has a unique prime factorization. i.e. 60's prime factorization is 2*2*3*5.

If 1 was a prime factor, then the factorization could be written as 2*2*3*5*1 or 2*2*3*5*1*1 or 2*2*3*5*1*1*1*1*1*1 or...

Prime numbers are useful for quite a few applications, especially including encryption.
