What odd number becomes even when you subtract two letters?
eleven
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.
What if you multiply an even number and even number what kind of number do you get?
If you multiply any even number by an even number, the product is an even number.
What is a conjecture for an even number minus a even number?
There is need for a conjecture. It is an easily proven fact that an even number minus an even number is always an even number.
What even number and odd number equal a even number?
Your question is incomplete. Adding an even number with an odd number will always result in an odd number. Multiplying an even number with an odd number will always result in an even number.
