What number is not even or odd?
Any number that is not an integer is neither even nor odd. For example, 8.5, pi, the square root of 2 are all neither even nor odd. Every integer (including 0) is either even or odd. 0 is even since it is divisible by 2: 0 / 2 = 0
If the sum of two numbers is even then the two numbers must be even?
If the sum of two numbers is even, the two numbers are either both even or both odd. A few examples:2 + 4 = 6 (even + even = even)2 + 3 = 5 (even + odd = odd)5 + 2 = 7 (odd + even = odd)7+13 = 20 (odd + odd = even)
If the product of 2 even numbers is even then the 2 numbers must be even?
This is not always true. If the sum of two numbers is even, then those two numbers are either both even or both odd. For example: 2 + 2 = 4 (even + even = even) 5 + 7 = 12 (odd + odd = even) 3 + 2 = 5 (odd + even = odd)
If you add 3 to an even number the sum would be odd or even?
Odd. Even + Even = Even Odd + Odd = Even Odd + Even = Even + Odd = Odd
Are rational numbers even or odd?
An even number can be divided by 2 evenly. An odd number will have a remainder of 1 when divided by 2. Rationals can be either.
Why are functions called odd or even?
Probably because polynomials and convergent power series in which all terms have even degree are even functions, and similarly for odd.
Can all the signals be categorized either as even or odd signals?
all the signals can not be categorized as even and odd,signals like voice we can not categorize it as even or odd either we can say it is a complex signal.
All polynomials have at least one minimum?
No. For example all polynomials of the form y=xn (or sums of such positive terms) where n is a positive odd number do not have a minimum.
How many counting numbers less than 30 are either odd or even but not both?
All numbers are either odd or even, none are both, so less than 30 there are 29 counting numbers that are either odd or even but not both. (Assuming you mean starting to count with 1.)
How many counting numbers less then 30 are composite but nei ther odd or even?
None of them. All counting numbers are either odd or even.
All polynomials have at least one maximum?
Not quite. The point at infinity cannot be regarded as a maximum since the value will continue to increase asymptotically. As a result no polynomial of odd degree can have a maximum. Only polynomials of an even degree whose leading coefficient is negative will have a global maximum.
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.
I hold playing cards in my hand, they are either all odd or all even but I do not want to divulge if they are odd or even, so I say all my cards are of the same xxxxx Does a word exist for this?
The word you are looking for is parity.
Is 895 an even or odd number?
odd number. 1,3,5,7,9 are all odd. 2,4,6,8, are all even
Is the sum of two square consecutive numbers an odd number?
Yes. One has to be the square of an odd number. The other square has to the the square of the even number either before or after the odd number. If this is confusing just plug in real values. In either case, an odd times and odd is odd. Therefore one of the squares has to be odd. AN even times an even, however, is always even. Therefore, the second square has to be even. Thus, one of the squares is even and the other is odd. An even plus and odd is always odd.
What does odd and even numbers have in common?
They have only one thing in common. By adding 1 to either an even number or an odd number makes them opposite. (even becomes odd and odd becomes even).
What number is not even or odd?
Any number that is not an integer is neither even nor odd. For example, 8.5, pi, the square root of 2 are all neither even nor odd. Every integer (including 0) is either even or odd. 0 is even since it is divisible by 2: 0 / 2 = 0
