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.
Why aren't all odd numbers divisible by 3?
Because not all odd numbers are multiples of 3 - I have shown you below that this is the case and you can see some multiples of 3 are even and some are odd and you can also see that there are even and odd numbers BETWEEN the multiples of 3. 1 (odd) 2 (even) 1*3 =3 (odd) 4 (even) 5 (odd) 2*3 = 6 (even) 7 (odd) 8 (even) 3*3 = 9 (odd) 10 (even) 11 (odd) 4*3 = 12 (even)

Can you express every odd prime number as the difference of two squares?
Every odd number greater than one is the difference of two squares. This includes all the odd prime numbers. To find the two numbers whose difference of squares equals a particular odd number, divide the odd number by 2. The two numbers are the integers immediately below and above that dividend. For example, 17 is the difference of two squares. Divide 17 by 2 and get 8.5. The two numbers are 8 and 9. 92 - 82 = 81 - 64 = 17.

If the sum of two prime numbers x and y is odd Then the product of x and y must be divisible by which number?
Prime numbers are usually odd.The only even prime number is 2.When two prime numbers are added say 3 and 5 the result wil be 8(even).So the question of ur answer is only applicable to the following set:2,3.The sum of an even prime and an odd prime will exhibit an odd number.2+3=5.When this two prime nos. are multiplied 2*3=6,it will be divisible by both 2 an 3.
How many prime numbers on a dartboard?

Can a whole number ending in 8 be a prime number why?
No, 8 is an even number. ALL prime numbers are odd numbers (excluding 2), that does not mean, however, that all odd numbers are prime numbers. Prime numbers do not have any divisors, even numbers do. Let's say the this number is 18. We know 1 and 18 are one set of divisors. But there are more: 2 and 9, and 3 and 6, thus concluding it is not a prime number. Short list of prime numbers: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53... and by now you should have noticed the pattern--all numbers that end in 1, 3, 7, 9 are prime.
What is the number 114 a prime or composite number?
Well, it's definitely not prime because it's an even number, and all even numbers are divisible by two.(FYI, even numbers are numbers that end in 0,2,4,6, or 8. Odd numbers are numbers that end in 1,3,5,7,or 9)So if it ends in a 4 (which is prime) then it's composite.
What numbers is a prime number 8-12-17?
17 is a prime number. 8 and 12 are not prime numbers.
