When you add them, you always get an even number; when you multiply them, the result is always odd.
false. it is always even
That is false. Two is a prime number and two is even.
it depends
The product of two odd numbers is always odd.
When you add three odd numbers, the sum remains odd because the sum of any two odd numbers is always even. Adding a third odd number to this even sum results in an odd number again. This pattern holds true regardless of the specific odd numbers being added, confirming that the sum of three odd numbers is always odd.
It is true that the sum of 2 even numbers is never odd
No, it is not true: it depends on what your numbers are.
Yes.
The GCF is, yes.
false. it is always even
Yes.
There are two truths about odd numbers. When added you get an even number... always! When multiplied you get an odd number... always!
True.
Yes, that is true.
No.
That is false. Two is a prime number and two is even.
My conjecture (an opinion based on incomplete information) is that the product of two odd numbers is 22. There is no requirement for a conjecture to be true.
