What the pattern called even odd numbers?

There is no such pattern because there are no even odd numbers. Odd numbers, by definition, are odd and therefore, not even.


What is an odd number that is also composite?

There are infinitely many odd numbers that are prime. Take any set of odd numbers greater than 1. Their product will be odd and, by definition, it will be composite. For example, 3*5*13 = 195.


Is the set of odd integers closed under division?

No. For example, 5 is an odd integer and 3 is an odd integer, yet 5/3 is neither an integer nor odd (as odd numbers are, by definition, integers).


What is the definition of even and odd?

even- equal odd- numbers like 3,5,7,9,11,etc.


Why do odd numbers can go into even numbers but even numbers don't go into odd numbers?

All even numbers have 2 as a factor - that is in their definition No odd numbers have 2 as a factor - that is in theirs. Trying to divide 2, or any multiple of it, into a number that by definition cannot be divided by 2, is a hopeless endeavour. There is no guarantee that you can divide an even number by an odd one, but it is not impossible.


If you add two odd numbers will the answer be odd?

No. For example, 5+5=10.


Is the greatest common factor of any two odd numbers?

The GCF of any two odd numbers is also odd.


Definition for the math word odd?

Odd numbers are those of the form 2k+1 for some integer k.


What is an odd number multiplied by an odd number?

A definition of an odd number is 2n-1 where n is any integer. The product of two odd numbers is thus (2n-1)(2p-1) for any numbers n and p. Expanding the expression yields 2(2pn -(p+n)) + 1. The term on the left is even by definition. Adding 1 to any even number is, by definition, an odd number. Therefore, the conclusion is elementary (Watson); the product of two two odd numbers is an odd number


Is the roduct of two odd numbers even or odd?

I guess you mean "product" - the product of two odd numbers is odd. (For example, 3x3=9, 5x3=15, etc.


Are all odd numbers divisible by seven?

All odd numbers are not evenly divisible by 7. Try 11, for example.


Are the factors of an odd number always odd?

Yes. An even number is defined as being evenly divisible by 2 (no fractional answers, only integers). If an odd number has an even factor, then because of the above definition, this odd number must have a factor of 2. But you will be hard pressed to find an odd number that is a multiple of 2, because that is already the definition of an even number. So, odd numbers cannot have even factors and thus odd numbers always have odd factors.
