What! Even numbers never equal an odd number. Not ever!

Yes, irrational numbers are neither odd nor even.

The product of two odd numbers is never even.

Even numbers.

Adding three odd numbers will never equal an even number.

23 is odd. A sum of two even numbers never makes an odd number. Likewise, no sum of two odd numbers makes an odd number. 23 can only be made by adding an odd and an even number.

This is not always true. If the sum of two numbers is even, then those two numbers are either both even or both odd. For example: 2 + 2 = 4 (even + even = even) 5 + 7 = 12 (odd + odd = even) 3 + 2 = 5 (odd + even = odd)

The sum of three whole odd numbers will always be odd keeping in mind that zero is neither even nor odd and that 'null' is not a number.

No. Odd numbers don't have even factors.

As long as one of the numbers isn't 2, adding any two prime numbers results in an even number. Why? 1.) Adding any two odd numbers gives an even number, 2.) adding an odd and an even gives an odd, and 3.) all primes are odd, except for 2.

yes

false. it is always even

Never. When you dont add the same odd number and even number of times. For example: 5 + 3 (2 odd numbers; and even amount of odd numbers ) = 8 5 + 3 + 7 = 15 an odd amount of odd numbers 5 + 3 + 7 + 9 = 24 another even amount of odd numbers. But never if you use the only same number

No. The opposite is true: the gcf of an odd number and an even number is always odd. All the factors of an odd number are odd; or to put it another way: If a number has an even factor, the number itself must be even. Thus the only common factors between odd and even numbers must be odd.

The sum of two odd numbers never makes an odd number. Only the sum of an odd number and an even number makes an odd number.

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

When you add them, you always get an even number; when you multiply them, the result is always odd.

The product of multiplication results in a number that has all of the factors of the two numbers being multiplied. All even numbers have the prime factor 2. Since no odd number has the factor 2, no product of those numbers can have it. So: - Odd numbers times odd numbers produce odd numbers. - Odd numbers times even numbers produce even numbers. - Even numbers times even numbers produce even numbers.

No, always odd.

Multiply two odd numbers Add an even and an odd Subtract an odd and an even

Odd numbers are always higher than even numbers . And even numbers are easier to add than odd numbers for some people .

There are two truths about odd numbers. When added you get an even number... always! When multiplied you get an odd number... always!

Yes the same as even numbers are in an infinite set

If you multiply one even number by one odd number, the result is always even. In general, if you multiply several numbers, and at least one of the numbers is even, the product is always even. This is because "even" means "multiple of 2", and if one of the factors contains a 2 as a factor, so will the product.
