Let even be of the form 2k and odd be of the form 2k+1. Then odd * even becomes 2k*2k+1, or 4k^2 +2k. This can be written as 2(k^2 + k), which is of the form 2k. Therefore, odd X even equals even.

Is f of x equal to negative x an even or odd function?
It is an odd function. Even functions use the y-axis like a mirror, and odd functions have half-circle rotational symmetry.
Why is when you subtract 1 from the square of an odd number it is even?
An odd number multiplied by another odd number will always equal an odd number. Therefore odd2 = odd x odd = odd number. eg 32 = 3 x 3 = 9. Take away 1 and you will have on even number.
Why even number squared will be even?
because that's the theory of maths even x even = even even x odd = odd even + even = even even + odd = odd
What is odd even equal?
odd even witch is terms for odd times even equals even
Would an even plus and even equal an even?
Yes it would Even + even = even Even + odd = odd Odd + odd = even

What is even times even equal?
even times even = even odd times odd = odd even times odd = even

Will odd times even factors always equal a product with an eve digit and an odd digit?
No. 2 x 3 = 6

Why are all multiples of 3 odd and even?
The multiples of all odd numbers are odd and even. Odd x odd = odd. Odd x even = even. Since odd and even numbers alternate, the multiples will alternate as well.
The sum of two odd numbers is always odd?
The sum of any two odd numbers is always even. This is because (a) any odd number can always be expressed as an even number plus 1, and (b) the sum of two even numbers is always even. So if X is even and Y is even then X+1 added to Y+1 will equal X+Y+2
Can decimal number can be even or odd?
Only integers are even or odd. If a decimal is equal to an integer (for example 24.0 is equal to 24), then it can be even or odd. If a decimal is not equal to an integer (for example, 24.1 is not an integer), then it is neither even nor odd.
Why does to even numbers equal a odd number?
What! Even numbers never equal an odd number. Not ever!
Even can be or can even be?
Only integers are even or odd. If a decimal is equal to an integer (for example 24.0 is equal to 24), then it can be even or odd. If a decimal is not equal to an integer (for example, 24.1 is not an integer), then it is neither even nor odd.
