Why if you multiply odd number with another number the result is always odd number?
Well, the question is why. The first number is "even" + 1. Multiply both of these by
your odd number. Now the "even" times "odd" is even, because every "1" in the odd
number becomes a "2". And then the remaining 1 times "odd" must be odd, which is
an even +1. Add it all up and you get evens everywhere except that final "1". So the
result is even + 1 which is odd.
There is a quicker way if you know how to multiply bracketed terms:
odd x odd = (even + 1)x(even +1)= even x even +even +even +1 = must be odd.
==========================
You've just read a truly impressive answer to a question slightly different from the
one that was asked.
The part of the question that comes after "Why if ..." is a false statement.
If you multiply odd number with another number, the result is odd number ONLY
if the nother number is also odd number.

Would 3 negative numbers be a positive number?
3 negative numbers are three negative numbers. There are a lot of things you can do with them: -- You can add them up. Their sum is always a negative number. -- You can add two of them and subtract the third one from the sum. The result could be a positive number or it could be a negative number. It depends on the three negative numbers you started with. -- You can multiply them all together. The product is always a negative number. -- You can multiply all of their absolute values together. The product is always a positive number. -- You can multiply two of them, and divide the product by the third one. The result is always a negative number. -- You can multiply two of them, then raise the product to the power of the third one. The result is always a positive number. -- You can divide one of them by another one, then raise the quotient to the power of the third one. The result is always a positive number. But, as I said at the top, 3 negative numbers are never anything else other than three negative numbers.

When you multiply and divide using only prime numbers is the result always a prime number?
No, never.
Why when you multiply an odd number by a even does it always equal a even?
When you multiply an odd number by an even number, you are essentially adding an even number of odd numbers together. Since adding an even number of odd numbers will always result in an even number, the product will be even.

Are the multiples of an even number always even?
Yes, assuming you're multiplying it by another integer. By definition, an even number is a multiple of two. When you multiply it be another round number, that even number becomes a factor of the result. That means any factors of that even number (one of them being two), will also be factors of the result, thus giving you another even number. If however you multiply by a non-integer, you may very well end up with something that is not an even number. For example, 6 is an even number, but 6 × 1.5 will give you 9, which is not an even number.
