What else can I help you with?
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).
Is the GCF of any set of odd numbers always odd?
Any set of odd numbers, yes.
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 numbers closed under subtraction?
No, the set of odd numbers is not closed under subtraction. For example, if you subtract one odd number from another odd number, such as 5 - 3, the result is 2, which is an even number and not part of the set of odd numbers. Therefore, the subtraction of odd numbers can yield results that fall outside the set.
What is set odd numbers?
1 is an odd number
Why is the GCF of any odd numbers always odd?
The GCF of any set of odd numbers is odd because odd numbers don't have any even factors.
How do i solve the set of odd numbers is closed under addition?
You can't. Adding any two odd numbers always gives an even number, which is not a member of the set of odd numbers.
What is the definition of even and odd?
even- equal odd- numbers like 3,5,7,9,11,etc.
Is the set of odd numbers is closed under multiplication but is not under addition?
Let + (addition) be a binary operation on the set of odd numbers S. The set S is closed under + if for all a, b ϵ S, we also have a + b ϵ S. Let 3, 5 ϵ the set of odd numbers 3 + 5 = 8 (8 is not an odd number) Since 3 + 5 = 8 is not an element of the set of the odd numbers, the set of the odd numbers is not closed under addition.
What definition proves that the set of all odd natural numbers is a countable set?
It is NOT a 'countable set'. It is an infinite set. 1, 3, 5, 7, 9, 11, ... you can count to infinity and keep going.
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.
