Yes.
To say a set is closed under multiplication means that if you multiply any 2 numbers in the set, the answer will always be a member of the set. When you multiply 2 odd numbers, the answer is always an odd number, so the set is closed.
It must be the same person asking these questions!

Give two reason for the set of odd integers is not a group?
Assuming that the question is in the context of the operation "addition", The set of odd numbers is not closed under addition. That is to say, if x and y are members of the set (x and y are odd) then x+y not odd and so not a member of the set. There is no identity element in the group such that x+i = i+x = x for all x in the group. The identity element under addition of integers is zero which is not a member of the set of odd numbers.
Which five odd numbers add to make fifty?
The given numbers are all odd. The sum of 5 odd numbers must be odd. 50 is not odd so there is no solution.
How do you divide 30 into 5 odd numbers?
You cannot. The sum of 5 odd numbers is always odd. 30 is not odd.
Are odd numbers divisible by even numbers?
No. because odd numbers don't have 2 as a factor but even numbers do. So it won't be a whole number.

Why are odd integers closed under multiplication but not under addition?
The numbers are not closed under addition because whole numbers, even integers, and natural numbers are closed.
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.
Are odd numbered sets closed under multiplication?
Yes
What is closed and not-closed under addition?
The set of even numbers is closed under addition, the set of odd numbers is not.
Are odd numbered sets closed under addition and multiplication?
No. 1 + 3 = 4, which is not odd. In fact, no pair of odds sums to an odd. So the set is not closed under addition.
Is the set of odd numbers closed under addition?
no
Are odd numbers closed under subtraction?
No, nor under addition, either. The sum or difference of two odd numbers is NOT an odd number.No, nor under addition, either. The sum or difference of two odd numbers is NOT an odd number.No, nor under addition, either. The sum or difference of two odd numbers is NOT an odd number.No, nor under addition, either. The sum or difference of two odd numbers is NOT an odd number.
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 are the composite numbers in the multiplication chart?
odd numbers subtraction
What set is not closed under addition?
The set of all odd numbers. 1+1=2
Is there a subset of the natural numbers that is closed for addition?
Yes. The entire set of natural numbers is closed under addition (but not subtraction). So are the even numbers (but not the odd numbers), the multiples of 3, of 4, etc.
Which set is closed under the given operation 1 integers under division 2 negative integers under subtraction 3 odd integers under multiplication?
1 No. 2 No. 3 Yes.
