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.
What else can I help you with?
When you multiply one number by another number the result is called?
The product.
What happens when you multiply a plus?
When you multiply a positive number by another positive number, the result is always positive. For instance, multiplying 3 (positive) by 2 (positive) gives 6 (positive). If you multiply a positive number by a negative number, the result is negative. Thus, the sign of the product depends on the signs of the numbers being multiplied.
What kind of number will always result when you multiply complex conjugates?

When you multiply two prime numbers the result is always a composite number?
That is correct.

What happens when you add subtract or multiply the digits in the number 42?
the result is always even
What happens every time you multiply a number by 10 and why?
The result always ends in a zero
What do you get when you multiply a positive number by a positive number greater than one?
When you multiply a positive number by another positive number greater than one, the result is always greater than the original positive number. This is because multiplying by a number greater than one increases the value of the original number. For example, if you multiply 3 (a positive number) by 2 (a positive number greater than one), the result is 6, which is greater than 3.
Would 3 negative numbers be a positive number?
NO!! When multiplying/dividing X - X - X = + X - = - Note ; when you mukltiply/divide the first pair of negative number, they produce a positive answer. To this positive answer you then multiply another negative number giving a negative answer.
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.
